I recently bought this coin as part of a small lot of contemporary imitations. It is a lead copy of a 1740 8 reales coin. Does anyone know if the fake was actually made around 1740, or was it made more recently? I can't see any test cuts/scratches that would indicate it was found in circulation and tested. Incidentally, here is a small selection of some of the other coins in that lot. I believe these ones are contemporary. 1915 George V Half Crown (Lead) 1818 George III Half Crown (Brass) Thanks!
