Here are a few pieces that came in with a mixed lot. I had posted a couple earlier (at the time of purchase) but now there seem to be more candidates for counterfeit. All the "silver" coins jump to a magnet. The copper pieces do not. Thanks!
I am not an expert in the series, but own many of the types. Not one of yours looks correct at first blush.All have something "off" about them, not to mention I see these types of coins at cheap asian markets regularly.
People often dump these flea market finds in lots on eBay. If they were cheap enough I would suggest keeping them as a point of reference for the next time you see something similar. You will benefit from training your eyes to instinctively spot the appearance of these things
Returning them gives the seller another chance to pass them off. I had this happen a few months ago with a counterfeit ASE. In the past, eBay would provide Buyer Protection refunds for fakes without requiring their return. This obviously invites abuse; I'm not sure how to craft a policy that wouldn't.
