Morocco Agencies Spanish Currency #21, 28 (SG#18, 25) 10c Purple on Red King Edward VII 1903-1906 Overprinted Gibraltar Keyplate Issue, VF Mint OG Examples of Both Watermarks
Very fine mint examples of the 10c purple on red from the 1903-1905 Crown CA Keyplate issue of Gibraltar, and the 1905-1906 Multiple Crown CA issue. Both examples are somewhat heavily hinged, but the remainders can likely be removed with a fine point pair of tongs, a lot of patience and care.
