1842 Go 8 Reales

Superb !!

It's not the first time I see those three dots :

The mint mark is the letter(s), usually one large and one small, immediately preceding the date. The additional punctuation between the date and the assayer's initials is known for the Guanajuato (Go) and Chihuahua (Ca) mints in the 1830's and 40's. There may well be others I've not seen documented. The 1831 Go had two stars instead of two small extra dots. I've never heard a satisfactory explanation of why this was done.

Interesting thing about the example posted by MathieuMa above is that the two extra dots are smaller than the third (like my Go), as my understanding was the Chihuahua version of this punctuation style was typically three large dots. And dated 1846 as it is, it's the latest with this feature that I'm aware of as well. But again, someone may know of even more and later examples. I also note with interest the lack of periods following each of the assayer's initials. I've seen a photo of an 1844 Ca with the same characteristic, albeit with the three large dots preceding, as mentioned previously.

Actually, the seller of the coin made that same suggestion. However, I think that interpreting it as such on a small portion of 19th century Mexican coinage is very much a stretch.

I'm having trouble getting pictures to load. I have a German blown glass beer stein with an 1846 Ca 8 reales coin mounted in the lid. Can someone help me use the optimizer on my iPad (if that even works)? Thanks, Bob
