Cleaning coins: DO NOT CLEAN COINS

[DanSmithCoinsUSA]

Cleaning coins usually kills a major part of the value

It is best to leave them alone and let a professional numismatist make an evaluation while they are in their virginal state of preservation.

I am always happy to look at images of coins...obverse (front) and reverse (back) pics are needed.

totally true

and I think olive oil is still the best way we can use to clean them without causing too much harm

I always heard you should use an ultra sonic cleaner with the coin in a plastic dish..with only one coin at a time....there is no contact to mar the coins. Is that true?

Are you talking about DUG coins?

Peroxide method will remove dirt from silver coins (as long as coppers are NOT mixed in with them).

Cleaning coins must be done to remove the dirt that can scratch the coin (silvers) or to stabilize (coppers). The BIGGER thing is to NOT field clean them to see dates!

Scrrrrrratch!

Coins I'm putting back into circulation are first put into a potato for 24 hours, then into Olive oil for 2 days, then Worchester sauce for a 3 days.

Then in the over for 12-15 minutes and 350 degrees

Clean with dish soap and water.

Clean with dish soap and water.

Sometimes cleaning a coin or relic with water is the Worst thing you can do.

clads & stuff going back in circulation Tumbler with aquarium gravel or glass bead media, a hefty squirt of Dawn. Roll em up & off to the bank. They don't have to be bright shiney. Even CoinStar machines will accept coins that aren't too dirty or too corroded.

Tip: re-check what drops out the return cup. Not sure about all of them, but the ones around here kick back missed wheaties. Think they are dialed in for the weight of clad. Anyone notice this?

 

[SusanMN]

Pennies and clad don't need to be cleaned at all. All but the crustiest pennies will run thru a coin machine just fine. I usually cash in $30 - $50 in coins at a time and probably get no more than a half dozen rejects.

Send them to me and I'll clean them up for you! LOL

Of course I will disappear with them before you know it!
