Hi, I have this 1888 Cn M Mexico 25 Centavos. I see in the standard catalog of world coins there is the error/variety listed of 1888 Cn M Cn/Mo.
I see in my photos the leg of a letter coming out the base of the C, to the left. there is also the remnants of a letter below the left leg of the N. any help would be great.
take care,
