The reales and escudos denomination system

Spanish colonial money ran on two metals: silver reales and gold escudos. Learn the whole ladder here, what each coin was called, and what it was worth against the others.

Silver

Reales: a half to eight

Silver was the everyday money of the Spanish Americas. The unit was the real, and the coins ran in a simple doubling ladder. The largest, the 8 reales, was the peso that the world came to know as the Spanish dollar. It is the coin sailors called a piece of eight.

Silver reales denominations
DenominationAlso calledWhat it was worthNotes
1/2 real medio one sixteenth of a peso The smallest common silver piece; everyday small change.
1 real one bit one eighth of a peso A single 'bit'. The peso was split into eight of these.
2 reales two bits one quarter of a peso The 'two bits' that survived as US slang for 25 cents.
4 reales medio peso half a peso Half of a piece of eight; less often seen than the 8.
8 reales piece of eight, peso, Spanish dollar one peso, one 'dollar' About 38 mm and 25.56 g of fine silver. The model for the US dollar.
Gold

Escudos: one to eight

Gold coins were the escudos, worth far more than silver and used for large sums. One escudo traded for about 16 reales, so a piece of gold moved real money. The word doubloon, from doblon or 'double', strictly means the 2 escudos coin, though most people today use it for the big 8 escudos.

Gold escudos denominations
DenominationAlso calledWhat it was worthNotes
1 escudo - about 16 reales, roughly 2 dollars The base gold unit of the system.
2 escudos doubloon about 32 reales, roughly 4 dollars Strictly speaking, THIS is the doubloon (doblon, meaning 'double').
4 escudos - about 64 reales, roughly 8 dollars A middle gold denomination; scarcer than the 2 or 8.
8 escudos double doubloon, onza about 128 reales, roughly 16 dollars The large gold coin most people loosely call a 'doubloon' today.

Pieces, bits, and two bits

  • A peso was the 8 reales silver coin, the piece of eight.
  • Each eighth of it was a bit, so one real was one bit.
  • Two bits was a quarter of the dollar. The phrase still means 25 cents.
  • The US dollar of 1792 was set to match this silver coin, which stayed legal tender in the United States until 1857.

What is the difference between a real and an escudo?

A real is the silver unit and an escudo is the gold unit. One escudo was worth about 16 reales. The 8 reales was the big silver coin; the 8 escudos was the big gold coin.

Why is a quarter called two bits?

The Spanish dollar split into eight reales, each called a bit. Two bits made a quarter of the dollar, so 'two bits' came to mean 25 cents in American English.
