Casascius coin (CSC) mint was recently under the zoom of US regulation authorities. As result the mint stopped to operate.
I thnik this can have significant impact on value of any Casascius coin regardless Casascius start to operate again or not.
Casascius fund the coin to specific registered BTC address and this fact is stored in blockchain with timestamp.
My theory is that CSC market value could strongly correlate with date of funding the coin multiplied by BTC amount funded. Similar to Bicoin days destroyed (

Of course Brass coin will have lower value than silver playted or gold playted coin. But in long run for coins in the same material cathegory, ''how old the blockchain timestamp is'' could be the strongest collerator of CSC price.
I assume here that coin is in mint condition.
What do you think?
