I found the buttons on today's hunt, but the Indian head and half are old finds. Just giving a few things to compare to. Anyone know anything about those buttons?
Nice find! Here are a couple for comparison that may help you narrow down the date a bit. The real to the left of the dime is a 1779 and is the same diameter, the one to the right is an 1817 and is slightly smaller (fits inside the rim) than a dime.
Mexican Carlos IV coins lasted till 1808; Fernando VII had the same bust/pillar coins 1/2s and 1Rs through 1821. Thereafter, they were Republic coins without the pillars. I've assumed the coin was from Mexico City.
Don...
PS: The IH is 19mm; a 1/2R is 18mm and a 1R is 20mm in diameter. Which is yours?
