    I use a vibrating cleaner filled with crushed walnut shells. Makes the coins look brand new!

    If you have a few special ones you want to clean, just get an old toothbrush and some toothpaste and scrub away the grime.

    If they're just old and tarnished I always drop em in some Tabasco Sauce about 10 min. Take em out, rub em off and they look brand new.

    If they're worth anything over face value, like what a coin collector would buy, DON'T clean them.

    Ditchdigger is correct on anything older. Unless it is just a newish coin to turn them in to a bank, never clean a coin. There are many coins in which a $100 value can be dropped to $10 just from cleaning.

    On a side note, if anybody needs any advice on old coins, I am a ANA and CONECA member and have connections with many of the top experts in the US.

    Many metal detectorists have the same issues as a lot of the coins that come out of the ground are pretty nasty. Some will use rock polisher tumblers. I've heard of some people putting the coins in a mesh bag and running them through a dish or clothes washer. I think people have had success putting them through coinstar type machines.

    Thanks for the help. I put them in a rock tumbler for a while and it worked great. I clean them so my bank can take them

    I just shove them in my pocket and spend them throughout the day. I had a bag of over $100 face that I had dug from metal detecting. I ended up mixing them in with my rolled coin that I take to the bank on occassion. I have a jug I toss change in and roll it up when I need some extra cash. I woud mic 5 or 6 bucks in with the 50 or 60 that I had to roll.

    In Florida there are no coin rolling machines at banks. When I lived in Illinois, every bank had one.

    Definitely never heard of ANY of these methods...all sound kind of interesting. Will have to try them out sometime.

    Right now, I just have a bunch of pennies, but to me, definitely is not worth it. I just spend them, or throw them away. I just save and collect all the silver change.

    Waiting to get one of those big water jugs that you see in office buildings. Mixed change, it can hold about $2,000 but a friend of mine, uses it just for quarters, and he said it is full, so I imagine he has like $4 to $5,000+

    I'm guessing, you meant that the toothpaste ate away all the grime.

    BTW, What kind of toothpaste is the best to use?

    Didn't really notice a difference with a whitening toothpaste, lol seemed like any old kind would work. Works really well for tarnished coins. I've heard before about the Tabasco and some other kind of sauce. That seems to work well also,,,

    What I mean is the customers really started bidding like crazy every time I'd throw a coin on there to sell,sometimes the bidding would just go nuts.

    As was stated earlier, the absolute worst thing you can do to an old coin with numismatic (coin collecting) worth over face value is to take a cleaner such as toothpaste to it. To an educated buyer this removes as much as 80 or 90% of the value from the coin-- often all the way down to just the precious metal content. Most educated coin collectors want to have little or nothing to do with cleaned coins and to those who buy the coin thinking it wasn't cleaned when it fact it was it is bad for the hobby and deceitful to the buyer who thinks they are purchasing something more valuable than it actually is.

    Even though it looks like it has more 'clarity' you are actually removing a layer of metal to make it more shiny and this is effectively defacing the coin and making it much less valuable. The tarnishing or toning of a coin can actually make it much MORE desireable to collectors in many cases.

    I found a 1978 silver dollar on a ditch bank a few years ago. Almost missed it because it was so tarnished it looked like a rock. I kept walking. Made it a few steps before going..nah, that rock was way too round. Dug it out and was quite surprised by the year.

    It's my birth year.

    Left it as is.

    Now I'm bummed because I don't have a clue where I put it.

    Hope it's not a sign of aging If it's anywhere around the house I'm sure you'll come across it.

    I have had luck puting sand 1/3 full in a glass jar and add coins then water till it is almost full,tighten lid and shake. Then pull out coins and save sand and jar for the next run.

    I ended up buying some coins from a person a few weeks ago. She ended up cleaning a valuable coin. It ended up costing her $300.

    With old silver there are 2 types of sellers (collectors, investors). By cleaning a coin you lose the collectors and just have the silver people. In the last year silver people have outbid the collector's but now with silver dropping the collector's are gaining ground again.

    Using the 2 pics above here is what I come up with...

    1942 Walking Liberty Half Dollar - Cleaned= Silver Value = $11.45 | uncleaned = $15
    1923 Peace Dollar - Cleaned = Silver Value = $24.50 | uncleaned = $35

    I know many of you probably don't care but being a coin person I have to say PLEASE never clean an old coin.

    Dont loose any sleep over it. Its not really worth more then a dollar. No silver content in that year to make it worth more.
