Chris Mcloughlin said this coin was very recently unearthed somewhere in Cornwall. I was asked to provide the finder with my opinion on what it might be worth.
The coin is a 27mm in diameter groat of Henry VII. On the obverse is one of the earliest profile portraits to appear on this denomination. It has single saltire stops on the obverse and double saltires on the reverse. On both sides the mint mark is a pheon.
The coin is an example of the regular profile type, which has a triple band to the crown worn by King Henry. In the Standard Catalogue groats of this type are listed as number 2258.
A profile portrait appears on Henry VII shillings, groats and halfgroats. I’ve seen a fair number of groats and halfgroats as detecting finds but have yet to see a shilling. If you unearth one in good condition then you will have hit the jackpot. It’s unlikely but you never know what the next bleep in the headphones will lead to.
Chris’s coin in a bit weak in places but is still clear enough to grade good Fine. In its present state of preservation it shouldn’t be worth any less than £220 to a collector.
