Historical Context
In 1798, Mexico was the richest colony of the Spanish Empire. Gold escudos were used in international trade and circulated widely in Europe, the Americas, and Asia.
The 8 Escudos was often called a “Spanish Doubloon,” though that term is used broadly for several Spanish gold denominations.
These coins were trusted worldwide because of their consistent gold content and precise minting.
Gold Content and Melt Value
With approximately 0.7845 troy ounces of gold, its intrinsic bullion value closely tracks the spot price of gold.
At a gold price of about $3,676 per ounce, the melt value is roughly $2,880–$2,900. Numismatic value is usually much higher depending on grade and eye appeal.

An NGC holder confirms:
- Authenticity

Value Range (Approximate)
Values vary widely by grade, strike quality, luster, and originality.

| AU | $8,000–$20,000+ |
