Value of 1991 10 Pesos "República de Puerto Rico" Coin

The 1991 10 pesos coin marked "República de Puerto Rico" is a commemorative / fantasy issue, not legal tender. Puerto Rico uses USD; it has never issued its own peso currency.

Market value (collectors):

• Good–Fine: $20–50
• VF–XF: $50–150
• AU–MS63: $150–300+
• MS65+ / Proof: $300–500+

Value depends on grade, mintage (likely low), metal (usually copper-nickel or silver-plated), and collector demand for "fantasy" Puerto Rican coinage. Not redeemable at face value.

Authenticate: Check weight, diameter, edge vs. known specs. Many replicas exist. Consult a numismatist or PCGS/NGC for grading.
