Starting another coin with lemon juice. 1 cap full to 1/2 cup of distilled water. Here are the before pics: [ATTACH] [ATTACH] And after 10...
5 days of distilled water (or is it 6 now?) and I'm seeing diminishing returns from additional soaking:
Ive got to be just missing this in my Krause catalog... can anyone help me ID this 25mm ish coin (roughly US quarter sized)? Thanks! [ATTACH]...
I always hope, but there's a reason the rare varieties are rare. Especially when looking at a 140 year old coin, the odds are the variety would...
Pics didn't upload properly, so I'll try again. This is the distilled water after 3 days.
The distilled water is working, albeit very slowly. Here are the results after 3 days of soaking. I thought nothing was happening, but quite a bit...
I'm trying to make sure that I'm not talking myself into this being a key date. What date do you make it out to be? [ATTACH] [ATTACH] I'm...
I'm terrible at grading these. Picked this one up in a foreign silver group. What grade would you assign, and how much is it worth in your...
How much did it set you back?

What is holding the iron oxide onto the silver and copper? These don't normally bond, so is it possible that there's an organic compound that's...
For Morgan #4, I'll give this a try.
Would there be a reaction between the iron and the silver or copper that's causing the rust to adhere? Or is it probably something like...
4 hr acetone soak. Had to refill again. The last remaining acetone was hazy and no longer clear.[ATTACH]
2 hour report on Acetone: Had to refill the glass, as about half of the acetone has evaporated and was barely covering the surface of the coin...
60 minute acetone soak: [ATTACH] [ATTACH]
Eh. You may be right about the cleaning. Closer examination under magnification does have more parallel lines than circulation alone generally...
20 more minutes (30 minute mark), no significant changes. I'm beginning to wonder if Acetone is ineffective against rust. Resetting the timer for...
10 minutes in Acetone showed virtually no result. Placed in about 2 ounces of liquid (enough to completely immerse the coin, at 60 degrees F, in...
