2020 Britannia Two-Coin Silver Proof Reverse Frosted Set, Coin Set from United Kingdom - detailed information

There are two Britannia silver ounce coins in this set - the "regular proof" coin, and the somewhat confusingly named "Reverse Frosted" or "Reverse Proof" variety.

The latter variety is actually "inverse frosted" - that is, the areas that are normally frosted (on both the obverse and the reverse) are mirror-like surfaces on it, and those that are normally mirror-like are frosted; it is issued in this set only.
