The maker is hard to decipher AM? AH?
There’s a leopard head
Then the dancing ? Type symbol
The letter year is M or B sideways
The last symbol? Sovreign head?
When looking at silver charts, I seem to find that the dancing type symbol but can’t find the matching letter so there’s a discrepancy and a leopard head in the same period. Also, the year seems hard to find to correlate.

Any input ideas suggestions appreciated.
Lots of the detail rubbed out, but it appears to be London, 1827 - leopard’s head for London, lion passant for sterling (not dancing - it’s on its side), date letter m, silhouette of George IV. I can’t make out the maker’s mark.

My feeling is that this is probably a fake mark. The main problem is the date letter in a circular punch. This is completely wrong for the purported date range. The lion passant punch shape also looks anomalous. The overstrike on the maker’s mark makes interpretation difficult; a good clean might help to firm up on opinions.
The lion passant punch shape might be explained by a couple hundred years of overzealous polishing, but I agree that the date letter punch is very suspicious, indeed.
