The mint mark is proving tough to identify, I am quite confident the lower letter is S which makes this a 1661S 8 Maravedis minted in Segovia, but I cant figure out what the top letter is, it looks like the letter E but I cant confirm this and searching is a blank. possible B?
I have put a sample of the same mint marks I found on a 16 maravedis coin just for comparison as the mint marks seem to be the same.
opinions ??

Values for the 1661S are quite high for this type according to NGC, but as it shows no pic to go with the ID I cant be 100% sure it is this exact combination of mint marks.
