1886 1 Peso Colombia

The 1886 Colombian 1 Peso was minted in .900 fine gold, a direct nod to the nation's recent adoption of the gold standard amid economic turbulence.

That made it a practical coin for everyday transactions, weighing in at about 1.69 grams and measuring 14 millimeters across. Its obverse typically bore the Colombian coat of arms, while the reverse featured the denomination and year, all struck at the Medellín mint.

Mintage figures for this year are murky; records from that era often went up in smoke during regional conflicts. As for myths, I've heard tales of hidden treasures involving these pesos, but they're mostly romantic nonsense from novelists.

Plan on finding one? They're not rare, but condition matters—expect wear from circulation in the coffee trade.
