Experiment Help

I don't see anyone here mentioning the potato technique. I'm not sure on how it's done exactly, but I've heard that coins can retone quite nicely by being stuck in the middle of a potato and baked in the oven. Anyone have the specifics on this?

I've heard of that method and I'm probably going to try the potato method.

This technique is called "Album Toning" and will take anywhere between 5 to 20+ years. I've only done silver coins and have no idea about copper.

1) Buy you a National Coin Album or pages (Wayte Raymond).http://www.meghrigsupplies.com/WAYT...BOARDS.html?

2) Insert coins and enjoy the hobby.

3)No need to check everyday for this type of toning will take time. Coins put into the pages will grade at the TPG's and they're consider NT.

Examples:

"What type of coins tone best in a potato?"
The type with lots of sour cream and chives.

I think I'll have to start looking harder for some silver before I eat my hash browns in the morning...

On an old set 09 Thur 40 pennies that I bought recently that was Ruined since they had green spots all over them. In-tire set was junk coins. I dipped them in vat murtric acid that pool cleaners use. The green went away but coins turned an strange yellow looking coin. I was unhappy with them and wanted turn them back brown again. I try ed lots stuff but it seemed it don't work on what I tryed.

1. I put coins in an oven and backed them inside an potato for serval hours.
It did not work. I tried to burn them for serval hours.
2. I took them again and tryed burn them with an propane torch for an little
while. I even dumped them in oil and tryed to burn the oil and coins at same time. It did not work.
3. I even bought that new stuff on ebay called coin tastic? It yellow stuff you smear all over coins with q tips. It turned them black but black stuff will come off of them when clean it with soap and water or rub with fingers. It was 6 buck rip off.
4. I even tryed painting them with wood stain but that was an waste of time.

I am to point I give up on trying tone them back to brown. I may try one last time to put them an box and just burn them for serval days when I burn down serval trees that fell down at my land. I may try to put in oil box and let them burn for serval days to try again.

All I can tell you on copper coins you will spend forever trying to change them back to brown. Maybe you can do good on silver coins but coppers are no fun for sure. I guess the rest of my set is stuck with green spots on them. I wish I knew an way for green spots to leave the coins. But intill then I am stuck with an Ruined coins with green spots on my junk set.

I'm going to buy that artificial toner from ebay. I'm considering practicing on some coins, and if I get it down tone an MS Morgan common date. Then send it in to PCGS to see if they grade it. Can you imagine if it comes back graded?

If I do this I'll share the results, and photograph the before, after, and (God help us) after being slabbed pictures. Oh, the controversy.

If you want to turn a Copper coin back to a darker brownish color, don't waste your time with junk on ebay. Just go to Walmart, Kmart of any sporting goods store where they sell gun blueing solutions. I've turned many coins into what almost looks natural brownish toning as if it was from just years of age. Some brands work better than others but I've had fabulous results from the brand from Walmart.
