[Question] How are people listing crypto stamps on open sea?

[frankbitcoin]

Hi everyone,

I can't seem to find this answer anywhere, was hoping you all could help me out.

I have several stamps I'd like to list and I see there's tons of listings on OpenSea.  These obviously can't all be the digital 'on-chain' only stamps.  How are people claiming the stamps in their wallet?  How do I do this with the physical stamps?

Any help is appreciated  

edit:  solved, locking.

Scartch them and claim.

After that the physical probably worthless. But you have the digital and can sell it.

Think the physical unclaimed have better value. You can sell them here.

Ah, didn't realize that.  Yeah I think unscratched is probably more valuable, as well.  Thanks JanEmil
