||"RA" is a shortened form of "IRA." "48" may translate to the date 1948, but it's just a guess. The only significant event for the IRA that year was the issuance of General Order #8 by the group's ruling council forbidding any armed action in the Irish Republic by their members. That was seen as a defacto recognition of the state. This coin is heavily corroded and shows spots of verdigris, but the legends are clear and readable. Purchased from Stuart Rainford / Heswall, Cheshire, UK. (Fb. 7, 2018) ($5).
