Welcome to Tnet.
It’s what we call a ‘tavern token’ (some folks generically call them ‘refreshment checks’). They were widely issued to address the problem that small change was often in short supply, such that if you had nothing smaller than a sixpence in your pocket, it was difficult to make small purchases. There was the additional benefit of a guaranteed return customer for the establishment that gave them to you as change... because you couldn't spend them anywhere else (except sometimes by local agreements between businesses).
Don has given you the pub that issued them and Erik has given you the maker.
T. Pope & Co, were manufacturers of tokens and medals, active between c1852-1881. They’re described in Slater's 1852-53 Trade Directory as being the 'successors to S. Hiron', at 52 St. Pauls Square Birmingham. They were at 14 Newhall Street between c1861-1877 and by c1881 had moved again to 35 Newhall Street.
