Now You Have Me Thinking 1945-P Jefferson

63/64 - Spot detracts considerably. Candidate for dipping?

Well so far that's higher than I had it.

That spot will not come out.

I'd probably try MS 70 first and see how it looks after that

Thanks guys, no it will not get dipped.

I need to backtrack on use of MS70 cleaner on Nickels... don't do it. I retested on a few Nickels last night and it takes away too much of the surface on Nickels. However, MS70 is outstanding on Dimes, Quarters, and Halves -- not good on Pennies or Nickels.

I've been using Acetone soak on Nickels and Pennies. I have had great results using dove bar soap applied with a distilled water and q-tip, pat dry with paper towel. Already sent in several Acetone or soap cleaned coins to PCGS and got back MS65 & MS66 grades.

Wait What , isn't bar soap considered cleaning ?

PCGS has a premium professional "cleaning" service where you can pay their fee and they will clean your coin. ...so, cleanings of coins do happen. They call it "Restoration" to make it sound premium. Here is their link: https://www.PCGS.com/restoration

However, any cleaning of a coin where somebody "wiped" or "scrubbed" the surface a little too aggressively will in fact kill a coin. The wiping or scrubbing will leave behind light scratches that show under 5x or 10x magnification and I've already killed a few test coins.

One item I found interesting from PCGS as they describe their cleaning service is that all coins have a microscopic layer of toning/grim/dirt or whatever you want to call it. That dirt layer in many cases is actually hiding marks. If you clean that layer off, you might be disappointed with the cleaned coin result. You could probably wait 50 years and your coin might reestablish toning that will cover over those marks.

And that is what will happen to your 1945 Nickel if you used MS70 cleaner on it -- you'll see tiny marks that the "dirt" layer is hiding. However, I'm finding Acetone dip on Nickels will not remove 100% of that dirt layer which preserves the toned look, just that your Nickel will look a little cleaner, with a noticeable shinier appearance.

Search "cleaning coins" on this website. That is where I started a year ago and learned the craft. Still learning. Experiment on coins you don't care for. People had some great suggestions including use acetone with an open window nearby, and keep all sources of flame away. I've already gotten sick from sniffing too much acetone. And wow, this stuff will flame up worse than gasoline so no smoking...
