They may be large or very small, might not even be visible in photos, but they are there. The plastic is there to protect the coin. If it has scratches, it means it served its purpose. If it's cracked I will write it in the notes and add a photo.I test all of the bullion items I sell with the Sigma Precious Metal Verifier Pro whenever possible. For all other coins and jewelry items I test them on the Fischer Goldscope SD 520 XRF. I test all my diamonds on the GIA iD100. Please be patient if I don't post feedback immediately, I always do it eventually.
Anything other than that can hopefully be settled with communication. Always please feel free to ask questions about my items, my past items, or other stuff I might be able to get.
