Hi!

When a physical stamp is bought on ebay (for example "Code [1]: 4ouHxo"),
is it possible the digital stamp (which is still in the first owner's ETH wallet) can be sold as well to someone else?

Meaning, the stamp "Code [1]: 4ouHxo" is physical sold to person "A" through ebay,
AND "Code [1]: 4ouHxo" is sold as well digitally to person "B" through "opensea.io"

And is there a way if you just have the physical stamp (of ebay) to transfer the digital stamp into your wallet,
since this sits in someone's wallet?

The same question but regarding a stamp bought through OnChain-Shop
I own a stamp "Code [1]: 71Qrnr", physical AND digital (in my ETH wallet)

Is it possible to sell "Code [1]: 71Qrnr", physically through ebay AND
sell "Code [1]: 71Qrnr" digitally through "opensea.io"?

Just wondering...

Thanks!

Regards
