An As is made from bronze whilst a Dupondius is made from a type of brass, making the dupondius more valuable. That's why a Dupondius was worth 2 As. The As and the Dupondius were of the same size, the only difference being the metal, and on an As, the emperor's head was bare or laurelate, whilst on the Dupondus, the emperor's head was radiate.
I'm so glad I stumbled across your blog. You do such detailed and DEDICATED work. Please give us more information about you and your profession. I sincerely hope you are well compensated for all of your skills.
Beautiful coin, I enjoy the history of them as well. Love your videos as they show good technique and they are very interesting and informative. Thank you
Denomination depends on the 1) weight (mass) of the coin, and 2) its size (diameter). Have you checked the ERIC catalogue (by Rasiel Suarez) and "Roman Coins and Their Values" by D. Sear?

Hi Nick, another amazing video. The 12 year old in me had a giggle at the fact it is an ass diva coin but really cool to see it transform. Pardon my ignorance but in terms of the difference of it being an ‘as’ or ‘dupondius’ what difference does that make in terms of the denomination by modern standards? Also, being such a well used coin what sort of things would this be able to afford? Thanks again for putting in all your hard work and sharing it with the world. I must say your videos are becoming my go to before bed views as they are satisfying, the music is relaxing and your voice over is so calm and chill. Thanks again and I look forward to seeing the next coin uncovering adventure ☺️
The light brown tiny flakes and in the grooves looks like it may be mycorrhizal fungi cell walls rather than dirt. Metals are useful to fungi at the molecular level in amounts that would not erode like an acid would. You could look with a more powerful transparent slide microscope.Perhaps you could see if the thin layer is cell walls. Also at an even finer level you could submit samples of surface layers for DNA testing. There could be DNA of the owner trapped as well. Then DNA from the world may show where it was handled. Those fungi may have seales DNA under it.
I'd be interested to see in a future video how you deal with bronze pest. It is a big problem indeed. What I generally do is alternate soaks in sodium sesquicarbonate (mix of sodium carbonate and bicarbonate) and EDTA, several weeks each. I have had moderate success with that - and future will tell if I'm wrong or not. So how do you do it?
Fascinating watching you working a coin, and it's strangley therapeutic along with the ambiant music in the background + you explain everything well...❤ your videos..thank you
Wow !! you make it look so easy, I have a bronze coin that i have been working on for 4 days, it has some type of tar substance on it, Your coin is silver, Question with your experience is silver coins easier to clean than others, or are they much the same, my experience is no where like yours, Thanks
You do you, but I have a couple tips; Start with a tooth pick or sharpened chopstick, anything _wood_, You are far far far less likely to scratch anything important. Second, olive oil is very good at softening up semi-organic materials in the dirt while providing a degree of protection against scratches. Water (even distilled) can cause a chemical reaction.
I currently have mine soaking in extra virgin olive oil. Alot of the crud just soaking is coming off. I know people have different ways of cleaning but I agree on the gentler cleaning as well. If I need to, I may use a blunted needle.
@@quietquitter6103Wow, chill. He was polite, providing constructive criticism. There are a million flavors in the universe - you don’t have to choose salt.
Keep going man! My 6 year old daughter loves your videos! I am enjoying learning about the cleaning process, and getting better myself. I would love a short video on tools and techniques, if you have one.
Nick, I already have an extensive restored Roman coin collection, but I want to get into restoration. Where is the best place to buy unrestored Roman coins?
I wish I had an answer for you! It's a mix of rare coin lot finds online from various sellers, or extremely selective ebay buying. I've had some luck on vcoins too but it's rare to find uncleaned coin lots. I want to make a video on this topic soon.
What a brilliant skilful man you are. A truly satisfying job. Please would you be kind enough to list all the tools you use and where they can be purchased from. Also is that Renaissance wax you use to preserve and polish. Your kind assistance would be appreciated. Kind regards Andrew
Great Job! I already cleaned and preserved dozens of roman coins and I have to admit: my equipment is very similar to yours :-). Cleaning a coin is always satisfying and it helps a lot if the patina is complete and hard, but this is not always the case. I would love to see a video of you trying to clean a coin with bad or even powdery patina. I already made some experiences here, but there is always room for improvement.
Really enjoying your channel. I use this same process with a binocular dissecting scope. I would like to know what tool you use and where to purchase them. Currently I use bamboo toothpicks sharpened, and steel dissecting probes/bodkins that I shape/sharpen on a stone. Thank you and best wishes from Missouri. Chris
Beautiful work. I was looking forward to this video. As of the period tend to be less than or around 10 grams, same for the dupondius. A sestertius will be around 20 grams in weight possibly down to 15. Based on the thickness, it is likely a sestertius. I have an As of Hadrian that I cleaned weighting only 9 grams. It is much thinner than your coin. A fiberglass pen is a tool you might consider. It can clean large areas pretty quick with a light touch.
Loved the commentary on this! I wonder the same as another commenter has asked... what would happen if you soak the coin in an ultrasonic cleaner? Looking forward to your next video!
In my experience ultrasonic cleaners destroy coins, but several people have mentioned this so I’m planning on making a video to demonstrate and test the technique.
This video blew my mind...for two reasons: first I've discovered your work with it, second I've feared to damage the coins I've found by revealing the shiny part which is the patina! I've always thought that I was damaging the coins by scratching the metal...but I don't have a nice microscope like yours BUT I think about it very seriously! Now...well now I'm back to clean some of the coins I've found! Thank you very much for the great work! Peace!

Denomination depends on the 1) weight (mass) of the coin, and 2) its size (diameter).
Have you checked the ERIC catalogue (by Rasiel Suarez) and "Roman Coins and Their Values" by D. Sear?
I would guess this is a sestertius given how thick it is.
I haven’t checked the ERIC catalogue but I will look into that! Thanks for the advice.
Recovery of Ancient Coins, very great find guys. the coin is beautiful with a dynamic design.

As a (new) coin enthousiast writing my (second) thesis on Roman coins, watching your video's is like meditating for me. Keep up the amazing work!
That is awesome!
Genuine question - would an ultrasonic cleaner do well to aid in the cleanup process?
What scope and process do you use for the magnification? Thanks for the video!
I'm very serious about that
Which tool is this one you use for cleaning? Congrats!
I love these coin cleaning videos, it started for me yesterday when i found an old copper 1 cent coin inside a ball of rust..
All the ruling emperors were described as beautiful out of fear of loosing your head. But that would only make sense right...?

Great stuff! Where do you get your dirt-caked coins? Would love to hear how these unknown coins come into your possession. Thanks!
Great video thank you for sharing. Where would one have coins cleaned in this manner in the UK?
Is the tool you use for cleaning a special pen? what kind? thx, have you a link were i can bye it?
Fascinating watching you working a coin, and it's strangley therapeutic along with the ambiant music in the background + you explain everything well...❤ your videos..thank you
I love collecting coins but I do not know much about ancient coins and how much are ancient coins usually worth
I'm surprised you don't use dental cleaning tools to scrape. Might be easier to hold than a needle!

Steam with distilled water might really get into those tiny spots.

Where do you get such cherry coins to clean?
Hey nick, you should let people send in their Roman coins and you could make a video and and clean it.
Great video! Where did you get the blunt needle you used (and any other tools you would recommend)? Also recommended magnifier with light? Thanks!
I dont know why it makes me so uncomfortable to see the grooves in the dirt on the coin while youre cleaning it. Like irrational fear or something
Hello, what material is the tip of the tool made of? copper? Thanks for your video.
Forgive me if this is a dumb question but could you use a ultrasonic cleaner to clean these?
Would it be good to start with a blunt bronze needle I wonder.
What’s The coins worth before and after cleaning ?
Where can I buy uncleanness coins such as these so I can try this method. Thank you.
Have you ever clean coins in Ultrasonic Cleaner?

In my experience it destroys coins.

Thanks for getting me into coin cleaning. I'll try it out myself with some victorian era common coins :)
Best of luck! “Modern”coins will most likely have a different patination so you may need to approach cleaning them with different tactics.

Nick like Corridor Nick?
You found me!
Hey Nick, do you think you could make an shopping list with links to all the materials needed to clean coins like this?
I've found a US large cent, but it's in terrible shape any advice how it can be restored or cleaned. It has to be wet to even see the bust.
Continue your work buddy, you are doing great videos, continue!
I appreciate it!
Fascinating.
Merhaba mail adresinizi verebilir misiniz. Müsadenizle bilgilerinizden istifade etmek isterim
I love it
Hi
Different diameters mean different denominations on the faustina coins...
I have Roman coin Octavia August Cesar
Great stuff, nicely soundtracked too.
Why not just use dry ice blasting?
I have a very very rare one need to test it carefully
Diva Faustina dupont.. I have this coin
You are the best, i ain't lying
No you are!

Where are you finding them bro
Very rewarding. Thank you.

It will last for another 2000 years now. Wonderful!
Would an ultrasonic cleaner help with this?
