I picked up a lot of 'junk foreign coins' and after going through them, these seem to stand out to me. I am not a foreign coin expert, but curious if anyone has any more information. The mystery coin appears to be a Brittish coin, but the reverse is worn off so I can't determine what it is. 1876 H Farthing. From research this might be a key date to the series, especially if it is the 'large 6' variety, but I am not sure what it is. 1881 Mexico 50 Centavo
