What does "WRL" stand for when written on coins?

"WRL" on a coin indicates that the coin is a reproduction created by Westair Reproductions Limited. Westair creates and supplies historical reproduction items to museums, gift shops, castles and historic houses all over the world. The company is based in the United Kingdom.

Westair Reproductions Limited began as an aerial-survey company that made reproductions of historic maps on the side. As the aerial-survey business declined and the demand for reproductions grew, the company began creating more items of historical interest. The company specializes in metal craft and creates coins, jewelry and miniature figures that are cast to be high-quality reproductions of the historic originals.
