Coin and Paper Money Collecting/cion mint mark


I have a 1822 8 real coin. On the back, after Rex G there is a dot with a small capital A above it. When I looked up the mint marks, they list G for Guatemala, but no A above the G. Does this have any other meaning?

Hi Wayne,
The "Ga" mint mark stands for Guadalajara. The coin you have is from Mexico, during the War of Independence period. For reference, it is catalog number KM# 111.3 in the Standard Catalog of World coins. There is also an over-date variety with the second 2 of the date over a 1.
Thanks for the question :)

My specialty is world coins from the 18th to 20th centuries, primarily non-US foreign coins and related areas such as errors and exonumia (tokens, medals, etc.). I can answer questions relating to identification, grading, selling, preservation and evaluation of such items. In addition to catalog value, I can give you the practical market value and trends for specific types of coins. I will also take questions regarding counterfeits (both modern and antique) and on how to identify them. I am NOT knowledgeable in paper money/banknotes, ancient or "shipwreck" coins. Thank you.
