Wearing down a replica to make it appear genuine

The 19th century forger Becker discovered he could make his product seem genuine by applying artificial wear.

It seems some modern forgers have relearned his trick. Antiquanova.com sells nice replica Neapolis staters for 45 euro in fine silver and 6 euro in tin.

A UK-based eBay seller has the following coin listed with 6 days remaining. Six bidders have worked it up to £26.00.
