Cleaning Coins With An Orbital Sander

I have a brand new ULTRASONIC cleaner with specialized high grade gunk remover: I figure if it can get stuff off brass cartridges without damaging them, then coins was the next thing it should be used for. :devil: :devil: ha ha ha!








And as the nice website states: and I paraphrase judiciously and without regard to truth: "This type of cleaning takes the very high frequency sound waves to get the gunk off when the bullet cases are in a liquid, and preferably our cleaning solution. The result is something called cavitation which makes a three-dimensional wave of first positive and negative pressures. These resonate and pop, imploding with as much as 50,000 psi of pressure. But being so small (microscopic, in fact) they do absolutely no harm to anything except the residues left on the used cartridges. When each cavitation bubble explodes, lots of jets travel as fast as most modern jets towards their targets. Nothing in the solution can escape being routed out (i.e. knocked off the cartridges so they get so shiny clean), all dirt is miraculously and permanently removed to the solution. This specialized and non-traditional cleaning gets into the crevices of the metal and other places cleaning normally can't and gets that surface debris off!!!"

While all of these suggestions can really do a great job at removing the gunk from coins, all of you have overlooked the easiest way to get rid of the gunk so that you will never see it again............

Sell the coins to a bidiot on FleaBay!

 

Strange stories !!!!!

 

Good choice! Not only will this clean them well, but they'll always be easy to find in a dark room.

 

I didn't know they made thousand dollar coins. Were they called deca-unions? What size were they? They must have been very unpopular due to their weight.:devil:

 

Maybe if you put it in a particle collider it will knock the gunk off or get the coin down to absolute zero. Another idea would be to smelt the coin and remake it.

 

this is how i feel when people clean coins and this is what i use to clean my coins

 

I heve seen some good tips here, going to try them on my coins right now.
Maybe if i add a little napalm the effect will be better

 

No joking, a lot of mail order companies sell silver dollars shined up with a Dremel topped with a buffer head, or referred to as whizzing. I do like the sandblast cabinet idea though. Looks almost like the satin finish mint sets of recent.

 

What a fun,light,and invigorating thread to read!!
Go Giants!!

Is that a CC? NOOO

 

what a load of wimps if you're going to clean a coin do it proper, a wire cup brush on a bosch hammer drill followed by soaking for a week in sulphuric acid

 

Have you even tried the nuclear bomb technique? It is by far the best one out of all the methods I have tried.

 

I tried putting an over-dipped Morgan in a PCGS genuine holder in a microwave last night for a minute or two--no change. But it did get warmer!

 

I coat my crusty coins in peanut butter and put them in a Hav-a-Hart trap outside overnight. In the morning I go and let the critters free and check the coins. Most times it works first time, but stubborn crud might take a few tries. Racoons do the best job.

 

I think I'm going to stick with my rock tumbler .

 

It would appear that we need a new organization like PETA or the ASPCA for the prevention of cruelty to numismatic treasures. There are some real coin sadists and coin torturers on this site.

 

pcnt?

 

These coins could use a good cleaning!

It works for Fred Flintstone...
