Let me correct that statement.. Some clipped coins don't show it.. See the difference? Most of them do show it.
Nice clip @FoundinTN! So I'm looking at yours and it reminded me of mine. You need a little verdi-care on that sucker. Here's mine, before and after...
The edge pics are indistinct, but you should look for the “punch and tear” characteristic. When a planchet is punched from a strip, the punch will initially cut through the metal, but as it gets most of the way through, the remaining metal will tear. This will result in the edge having a partially smooth surface and what appears to be a torn surface (I’ll leave it to the metallurgists to provide a detailed explanation). This is a good way to distinguish between a coin that was ground vs a true clip that doesn’t exhibit the Blakesley effect. Also, look to see if there are any striations or displaced metal pushing up along an edge that would indicate abrasive grinding
Look at the initials on the reverse. Hard to say if it’s a case of over polishing, partial fill, or Blakesley. But in the right spot. Rim looks full though.
Well if you mean be a TPG'er conservation, no. My stepped conservation was acetone bath, distilled water rinse then verdi-care.
