Absolutely beautiful. And people wonder why I think America needs to get back to beautiful designs. That coin is a perfect example of what a coin should look like.

 

Is this a Bullion currency coin or is it used in commerce? It's about the best looking modern design i've seen, but gold is a bit pricey these days. In fact it's a great time to sell all bullion you can park it in a money market and wait for the price to drop.

 

toilet bowl cleaner

I was searching the forum for toilet because I wanted to see if anybody had posted about putting coins in toilet bowl cleaner. Another one of my few posts came back in the search relating to an auction I had lost for an UNUSED lucite toilet seat with coins in it. I don't know why my posts frequently relate to toilets.

Anyway, I got a 1996 quarter today in change. It is nothing special except it was really dirty. It had black stuff on it and just looked terrible. I thought to myself I should try and clean this. I remembered seeing on the internet a penny that was soaked in toilet bowl cleaner turned out to be very clean after it was taken out.

I put the quarter in a cheap plastic party type cup. I poured on some toilet bowl cleaner. I was looking through my closet and found another brand of toilet bowl cleaner and poured some of that in too. I decided to throw in some JFK half dollars that were dirty (I had just gotten about $340 worth in rolls from the bank). I let those sit for about 15 minutes. I went over 15 minutes later not realizing I could smell this from like 5 feet away I took a breath and it just about knocked me over. Very strong chemical smell to say the least!

I poured the contents of the cup into the sink and was surprised to see most of the dirt came off.

I want to try another experiment and put those same coins in the toilet bowl cleaner for like a week and leave it in my backyard because the kitchen didn't smell so good after I conducted my first experiment.

Would a weeks worth of soaking remove some of the coins high points, like the date?

Anybody have a link to experiments on coins soaking in chemicals?

I saw on Mythbusters they tested Coca Cola in various things and one was cleaning a penny... the Coke did nothing in the penny cleaning test.

Also, sorry to bring back this post but I read somewhere it is better to reply to a current thread than to start a new one.

 

Nate,

Soaking coins in anything but acid will not remove metal. While it will turn the coins ugly colors and remove luster, it will not eat the coin.
A while back, I soaked a gold coin in bleach for two weeks. Came out the same it went in. Just a bit off in color.

 

But remember, that doesn't mean you can use everything that lacks the word "acid" in its name! Lemon juice contains citric acid, some commercial cleaning compounds contain phosphoric acid (among other bad things), ketchup and tomato sauce have acidic components, etc., etc., etc. Anthing with a pH below 7 can eat metal. The only difference between sulfuric acid and tomato juice in that respect is that the tomato juice will do it much more slowly.
