How to Identify the Peso
- 1). Look at the shape of the coin. The single peso is a completely circular coin that has smooth edges and is 21 mm in diameter.
- 2). Examine the design. The single peso has the Mexican national shield with the text "United Mexican States" inscribed directly above it.
- 3). Check the denomination. The single peso has a "$1" on its face. The $2 Peso has almost identical design except for the denomination.
- 4). Compare colors. Single peso coins have two colors of metal: a stainless steel alloy around the outside, and a bronze alloy on the inside.
