That's quite a beautiful collection.
Some day my coin collector buddies are going to wonder why they didn't act on my recommendation to grab a couple of these while they are still:
a.) using
"early coins" (funded with transactions in 2011 and 2012)
and
b.) still being made (e.g., Rev 1 of the One BTC coins are either done or near done being produced, as far as I know -- or at least of a limited quantity for a "key date"/first release.)
The coins shown in the picture are for sale. I live in the Netherlands. The Revision 1 coins, as collectibles, are for sale at 1.9 Bitcoins per casascius coin. I can probably send to other places in Europe but have little experience with pricing, customs (?), etc.
Contact me for details, if you're interested
