Rock Tumbler Or Ultrasonic Cleaner For Dirty Coins

[Burky]

I see both opinions on other threads. Any before and after pictures of either method with dirty/corroded coins? My bank would take the coins but they need to be clean. These pennys are two far gone, just using for an illustration.

I take my nasty looking coins, those that look like your penny's to my local Coin Star machine and get a Amazon e-gift card, there are no fee's with the Amazon e-gift card.
But if I was to clean them I'd use Rock Tumbler, we use a rock tumbler to clean our tokens. You can get a Rock Tumbler for $60 at Harbor Freight.

Rock tumbler it is. I was at the coin star this AM and had counted approximately 1/3 of the coins. The amount I received on my gift card was about $25 less than my estimated value based on the ratio of the coins I counted. I had the opportunity of seeing one of those machines open with the Coinstar tech working on some thing. The amount of change inside the machine laying on the bottom was incredible. That is money that I presume never got counted

I know some people that reload ammo and use the vibrating polisher. Some of them add about a tablespoon of nu finish car polish to the media before they add the brass and it supposedly really helps shine the casings up. Just something to try when you get bored.

Nothing is going to "clean" those pennies. That's not something on them, that's the copper gone from the surface and the zinc corroding. They are going to get rejected by the CoinStar or bank counter no matter what.

I usually give mine a 10 minute soak in CLR and then rinse. That does the trick for 95% of them.
