I recently acquired this 1875 Seated quarter. The surface is coppery in color (photos are essentially accurate to color). It has an 'X' cancellation-type mark on each side. And it weighs 5.87 grams; genuine Mint State examples of this type weigh 6.25 grams.
2/21/2023 Update. I knew the answer to this question before posting this blog post. :)
Requests from commenters:
(1) Specific Gravity. I completed this on Tuesday, 2/21/2023. I did this test 3 times. This was to ensure overall consistency in the methodology, and to account for any variation therein. For example. the string (which holds the coin) absorbed slightly different quantities of water each time, and I accounted for this in my final calculation. Results will be shared soon b/c this seems to be THE test many of you want to see. SG for 90% silver = 10.31. SG for Copper = 8.96.
(2) Counting the Reeds. I can't locate a large enough parabolic mirror, and a bit of the edge is too distorted, presumably from the chisel marks, to fully count them.
(3) Toothpick test in the chisel grooves. Unfortunately, my attempt to 'clean' these areas with a toothpick and a cotton swap proved no match for the decades from dark build-up in this area to resolve whether the interior of the planchet is silver or something else.
The question for the group is - Based on the photo and the above information (and I'm sure I could add more info if asked), is this piece Genuine or Not Genuine/Counterfeit?
Please answer in the comments below and provide an explanation for your opinion/answer. Possible hint - rummaging through Bad Metal Silver might be an asset here...
I'll create a follow-up blog post in about a weeks time summarizing the answers/comments and I'll provide my opinion.
Good luck,
Winston
