I'm terminating the acetone test. After 30 hours, the rust appears to be unaffected. The fields may be slightly more pleasant to the eye (any...
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...
I always cringe when I see stamped coins, but this one was interesting enough to add to my collection. I don't know what the history of these...
I'm trying the third Morgan (an 1885-O) in Acetone. I was surprised to find that Acetone is sold in steel containers, as I thought it would be...
Status of the distilled water soak after 24 hours: [ATTACH]
Thanks. I had read that a glass bowl & heavily ventilation are recommended, but it's worth remembering that other collectors with a similar...
Yeah, I was surprised too. There have been some weird price inversions in the gold and platinum market lately, driven largely by bullion prices...
You can also check recent Heritage sales. Jan 11, 2019, one sold for $2,280:...
In hand, neither looks cleaned. They are certainly both circulated, but the wear looks honest. And at $28 apiece, I feel like they were both well...
Before I try an acetone soak, how do I neutralize acetone after taking the coin out? Does it evaporate away under room temperature? Or should I...
Interesting. I'm definitely not trying the same method on each Morgan. I want to see how each works and compare the results. I will *not*...
I recently picked up a pair of 1894-O Morgans while Cherrypicking from a gold/silver bullion store. I'm thinking about keeping one and selling the...
