Possibly Unique Scottish Mule Silver Penny (Any Scottish Coin Experts Here?)

Coinlover101

Scotland, Alexander III, silver penny, second coinage, c. 1280-6, class D2/M mule. 26 point reverse, Berwick-upon-Tweed. 1.35 g.

The number of points on the reverse is statistically significant and has long believed to have given the mint attributions. 26 point coins are usually attributed to Berwick-upon-Tweed. This appears to be the only example known from the mint struck as a D2/M mule, which in general is an extremely rare pairing; mules of the classes are usually the other way around (i.e. with class M obverse dies)

VF, bright metal. Excessively rare mule, perhaps the only known example, and a coin of academic interest.

Spink 5057/5055 (obv/rev), Burns -, absent from the Hunterian and Ashmolean collections.

Nice coin - back when Berwick upon Tweed was a Scottish city and mint. There are some fascinating hammered rarities in the Scottish penny series
