I'm surprised the bidding isn't more competitive on these. These are great coins. Unlike some, they're not just Casascius clones -- arashd came up with refreshing new designs, in a new size, with truly excellent production values. That's saying something, in a niche market where sometimes "limited edition" basically underscores how home-made a thing is. Plus, laser engraved public & private keys, with matching QR codes! Even the protective stickers followed a different model -- not the regular holograms, but more of a multi-layer, scratch-off kind of thing.
So I guess what I'm wondering is why Casascius coins seem, so far, to command more interest, when those are so much more common. These are much rarer, and should command a premium. And they deserve it.
I am *guessing* that it has something to do with trust -- because these are less well known, people are slower to bite? Well, for what it's worth, as someone with the dubious distinction of having opened a few Nolacoins in the past, I had no issue whatsoever redeeming them -- and that is NOT always the case. I won't name names, but sometimes... stuff. With Nolacoin, keys were correct, the QR codes worked, and arashd earned my trust.
I'm not plugging my blog, but for what it's worth, I wrote about Nolacoin a few years back in more detail, and I think what I wrote is still relevant:
