Watch List notes:

AZORES: António I, Claimant, 1580-1583, AR 2 tostão, ND [1582], Gomes-An.26.01, falcon countermark on Gomes-E1.50.07 tostão (100 reis) host, PCGS graded AU on VF host, RR. The countermark on this tostão is a falcon ("açor" in Portuguese) which became a badge of the Azores. Initially, the falcon was the mintmark of the Angra do Heroísmo mint. Later, it was used as a countermark to indicate that Portuguese coinage struck outside of the Azores was valid for circulation there. For this particular type, the countermark also indicates an increase (doubling) of the value.

Estimate: 700-900 USD
