Thanks. I've assumed as much.
Just curious if those ever going to fetch 2-3 BTC again how would one go about selling / buying such asset ?
Any physical items on similar value (200-500K USD) that were sold here ?
No, never... current premiums on brass Cas coins is 0.05
BTC or less.
If this reward is worth the risk for you, you would still need to figure out logistics of transferring the coin and costs incurred by doing so.
