How many Casascius 1btc error coins remain active? Collector value impact?

[Possum577]

Of the 11,000 Casascius 2011 series 1 1BTC error coins minted, does anyone know how many remain active? And how will this impact the collector value of the coin?

Thanks.

Hard to know which coins are which but it gives you an idea overall.

Considering the errors were the first then it's likely more of them were opened as they were worth less.

Thanks, but the Uberbills site doesn't tally the count of series 1 coins. I was hoping someone may have already tallied them up or knew the answer first hand.

I think that could only be known by casascius himself, many buyers that received an error coin havent talk about it. but i think less than 20

May I ask what do you mean by error coin?
What was the fault? Was it something about the coin itself, or the bitcoin 'inside' it?

@benjig, so out of 11,000 produced you think less than 20 remain active?

In small and repeated writing on the hologram on the back of the coin, Casascius was misspelt Casacius. That's the error. It was corrected in the series 2 coins.

It's very rare to see a redeemed one up for sale, especially with the remains of the hologram. The vast majority up for sale are intact.

@gentlemand, that's what I would suspect too. Although it seems like a fair portion may have been discarded or lost simply because the were handed out to the "uninitiated" or thought of as mere novelty at the time, but my guess is that half to 3/4's still remain active and firmly in the grasp of owners.

I honestly think most are still active. I've seen very few people selling redeemed ones and although they're not listed on the marketplace or for sale on different sites the whole time, most if the time they are unredeemed with the hologram intact. Their was quite a high montage of them, and since they were made in the early days, I'm assuming the early adopters were the majority of the buyers and therefore most probably still have them.
