I will only be taking set #14 as I'd like to add this to my collection. If anyone wants it #15 is now available.
I will post pics when I get them.
I do like the nickel black option not sure if there has ever been a coin with that finish before.
On another note this is also the first time a coin set comes with one BTC address/PrivKey.
I do understand some people may not like that, and of course need to be careful if some try to resell single coins, and private keys were handled by the mint.
However this doesn't necessarily mean the mint actually knows what the private keys are for and/or they will be dishonest. But better be safe than sorry.
I wasn't going to fund them anyway, as many other coins I see being sold on the forum, if they came as DIY or unfunded, I never seen one that was funded by the buyer.
For collection purposes this is rather unique (in my humble opinion), coins look great, a nice first ever black option, something different from all other coins... although unexpected.
The OP also mentioned this was a mistake, being the first coin production and all, maybe miscommunication with the mint side (not sure).
He has also been very accommodating and open, lucky this was discovered before any single coin was sold. And for $60 per set it's cheaper than many others.
These should be considered error coins maybe? What do you guys think? I'm happy to have them in my collection nevertheless. (Looking fwd to get them)
I'm aware there will be a new series so looking fwd to that, with the lesson learned I would expect something interesting.
