Also Casasicus, Memorydealers seems to no longer sell any of the coins for fiat currency, any idea on that?
I have never explicitly asked why not, but it seemed kind of obvious, there were a lot of things that led me to guess that it probably wasn't worthwhile, and that his "opportunity cost" to promote Bitcoin might be better expended doing much of what he does now.
The fact that I didn't have a lot of markup to offer, coupled with seeing his resources tied up having to filter an endless stream of fraudulent orders, probably made it a big hassle. His shipping department is best suited for cranking out shipments of high-value computer parts - favoring expensive heavy boxes as packaging, FedEx over postal mail, employees trained to get serial numbers, prepare packing slip/invoice, and take photos of everything going out the door as standard operating procedure... all of that is a pain in the ass and a major labor expense just to make 5 bucks on a bitcoin, and that's all before factoring in the customer complaining about the markup and the "unreasonable" shipping cost, being threatened by PayPal (it happened), and having to deal with almost guaranteed chargebacks. Oh and I definitely can't forget the fact that the web store had to be constantly updated every time BTC/USD would swing, and being slow to update on a huge upswing would result in large opportunistic orders that would be a pain in the ass all by themselves.
If he found selling my coins to be a waste of opportunity, I can't fault him for what he's doing instead: BitInstant is responsible for making it less necessary to sell for CC/PayPal in the first place. If he could be said to have created a problem by letting his web store run out of Casascius Coins, he has more than solved it by helping to bring Bitcoins to thousands of locations in 30 countries, and at a better price too, given BitInstant's fees are a far smaller markup than the premium he had to charge at MemoryDealers to even consider selling the coins.
Nowadays, with BitInstant making bitcoins so accessible, someone "willing" to pay the equivalent of 130 BTC just to buy a 100 BTC bar with credit card is so likely to be fraud it's pointless to even offer it. If there's a "right way" to sell Casascius Coins for credit card, it would probably be to offer ONE COIN at a decent markup, knowing the buyer is willing to pay a premium to own one or give it as a gift, and be willing to ship it only to the credit card billing address.
(just a suggestion
