Here's a coin from the losing side of the Battle of Puebla: France 1862 5 Centimes Napoleon III If you feel like it, please post an 1862 coin from anywhere in the world!
Dug through my "late 1800s" bin and found a few more: From top L: One Cent India-Straits (Malaysia), Quarter Anna India, 10 Centesimi Italy, 5 Centesimi Italy, 8 Pesos Honduras (Provisional), 5 Centimes Belgium x2
Mexico, Eight Escudos 1862, Durango Mint, Hand on Book style Gold, 37 mm, 26.95 gm Spanish Eight Escudo coins were called "Doubloons" and this would be a "Mexican Doubloon". The coin has circulated quite a bit from it's wear and scratches. It is interesting to speculate where it has been since 1862.
Found a couple more: US One cent, 1862 Kingdom of Lombardy-Venetia (Austrian Empire), 5/10 Soldo, 1862
