PSA Pokémon Card Real or Fake?!

I'm fairly new to collecting PSA slabs, so when I noticed that my recent PSA slab did not have a little knob on the bottom, I became a little worried.
I'm not an expert on the subject, but I'm happy to share my very small knowledge on things to check for when purchasing a PSA slab.
Please comment below and share any additional information regarding how to check for authenticity on these slabs.
As always, thank you for watching and take care.

If the card you're holding matches the scan on the psa website then it's legit.
The psa website doesn't lie

Thank you that gives me a peace of mind 🙏
