Coin 1: Reported weight close to 17g which is alarming by itself. Note the scratch on Apollo's neck. Coin 2: Reported weight around 14g, the scratch appears again. Coin 3: Reported weight close to 17g. There are even traces of overstriking (can't tell the undertype). The scratch is there. Coin 4: Reported weight around 14g. Again the same scratch is there. I think it might be the parent of the others. I kindly ask @Barry Murphy for his opinion (with many thanks in advance).
