This set contains four of the denominations of silver Britannia proof coins issued in 2025. The proof pieces have a reverse design which differs from the standard ("bullion-grade") Britannias issued the same year.
The coins in this set are "reverse frosted" (which actually means they are inverse frosted - where a normal proof would be frosted, they have mirrored surfaces, and where the surface of a normal proof is mirrored, they are frosted).
The set contains four coins - a silver ounce (not fractional) and three of the fractional silver Britannias - quarter, twentieth- and fortieth-ounce (skipping the half and tenth-ounce sizes).
The set comes in a black presentation box, with a numbered Certificate of Authenticity. |
