This is a TALLER silver coin.
Those silver coins, together with other material goods were used to buy slaves.
Nowadays they are used in several african countries as jewels or ornaments, even good luck charms.
I once saw an Houngan using one of this coins in the ritual to buy Souls for butey zumbí or dead spirit bottles.
A silver coin (owó laka) of whatever kind now, even if traditionally it was a peso macho, is used in Cuban Ifa rites to honor the Eggun, the ancestors and is tossed on the ground to begin the “honra”.
Many thanks to Maria M for the gift.
Merci anpil jolie femme!
