New Discovery and UNIQUE: Proof Great Britain 1967 Sixpence

Recently turned up is this now-certified GB 1967 Record Proof Sixpence. Not known or recorded, it allegedly turned up in a 1970 proof set with all other coins in the set of normal type.
Highly unusual, what would it reach at auction if publicised? Yikes.

    A 1967 coin was found in a 1970 proof set? Seems strange and almost impossible.

    Yes, I would suspect. Verrrrry strange. I looked at my 1970 proof set and, well, NO special 6d or other coin.....

    This coin is right up my alley and have never heard of ANY 1967 Record proofs "in the wild" under any circumstances.

    Interesting coin.

    I try to use the term "unique" sparingly and usually qualify it as "probably unique." I have learned the hard way that the Royal Mint made many treasures for many people at many different points in time, including post-dated treasures and restrikes.

    Agreed. But it is odd that such a special thing would end up in a seemingly-normal proof set.

    As do I. I think this one may have gotten out by accident as the 1970 proof set it was in was supposedly quite ordinary and was not made to special order. Also, the coin unknown for now basically 60 years.

    Very cool. FWIW, I would guess it would bring about $5000 at auction.

    Maybe it started as a Proof of the frozen 1967 date ahead of the issuance of the 1970 proof sets proper, and someone mixed it up with the 1970 coins by mistake

    Could be except that I don’t think any other 1967 proofs are known. I tried looking at Royal Mint collection and couldn’t not find it or any others of that date.

    67 business strikes apparently aren’t known either.

    Strange… one can not help wonder if lightning will strike twice. Seems plausible there could be others. But why would one surface so much later. This could even be more mysterious than the 1971-s type I proof which may have a known population of 25-40… if that.

    Experience the World through Numismatics...it's more than you can imagine.

    Quite a few coins in the Royal mint collection are most likely proof or at least specimen but are being described as currency, for the sixpence Im not sure there's one who could be a low-quality proof or just a well struck curency strike but for a few others (florin, threepence, halfpenny) Im quite confident the mint is holding proofs.

    Sorry, I missed it in the catalog. There were indeed business strikes dated 1967.
