An OG collector, don't see many of you around these days. There is certainly still a market for higher valued coins though it is fading as the price of bitcoin rises. Delivering the coin is best done in person, so you may have to hop on a flight for the sale (or have someone trusted do it for you). I think a lot of these are being peeled due to the complexity of a sale. If you do peel, try and leave the hologram intact as much as possible, it greatly increases it's value. You might expect to get $200-500 , which always varies greatly depending on a number of factors. That is if you even want to sell it. I'm not sure what the last one sold for but I'm sure MinerJones will chime in and share that info. Cheers.
Last I remember was Anduck having a few of the errors sold/auctioned here on the forum.... but think they were ICG slabs, not ANACS.
As it stands, I have seen some raw coins go for in the 1.2 range, showing that premiums are slowing picking up.
I would think that now that they (ANACS) no longer grade crypto, this may lend itself to getting a higher premium.
And any exposure on a secondary platform can also increase this, as we have seen on places like Scarce City and Ebay.
