1974 Commemorative Weird Colors, Silver?

@p1000, first welcome to CCF. Second, just to be clear, you have shown pictures of two different tokens, right? The bottom one looks like a partly gilt, frosted proof. The top one, as you describe, has toned into a mixture of red, orange, blue, and green coloration. Some collectors will pay more for attractive toning, but I'm not sure that this qualifies as "attractive". I'm sure others will weigh in on that. It looks like this token was made in both bronze and silver. Yours certainly is silver on the outside, but you would need to compare weights (30.7 g for silver) to most easily determine if it is silver or silver-plated bronze.

Hi thank you for your reply! The pictures are actually of the same coin, only I took the pictures in pairs. I wanted to show what it looks like in the light using the flash on my phone, and then show what it looks like without any light directly hitting it. I weighed it on a digital scale I have and it comes out to 31 grams or 1.1 ounces. This scale is a post office scale that you plug into the computer so I just laid the coin down and got the reading. I looked at a coin on ebay which appears to be the same thing, or looked the same only to be completely shining silver. This is what it said about that coin:

Authentic United States of America
JOHN ADAMS, 200 Years of First Continental Congress Commemorative
1974 Proof Silver Medal 37mm (30.74 grams)
AMERICAN REVOLUTION BICENTENNIAL JOHN ADAMS, Bust of John Adams left.
FIRST CONTINENTAL CONGRESS #9702; FOR THE RECOVERY OF OUR JUST RIGHTS #9702;, Patriot standing right, holding papers and feather pen.

I hope I am not violating any forum policy buy putting that, but that coin is selling at like 50% off at $180, while there are others that are the same thing selling for just about $25-$30. Pretty confusing is all I can say.

I would have to say, though I am more so confused as to the way that it looks. It weighs the same as silver, yet only the higher parts of the coin, or as you called it, "frosted" have that silverish look to them underneath the odd coloring. Is there anything that I can do to remove this or should it be left alone? Thanks again:-)

I quick dip in E-zest might ...or might not help. When dipping you can
never be sure what the results will be. It might take all the toning off,
or it might leave some. If dipped to long it can leave a dull look.

I would not use it for the first time on anything that might have any value, be it sentimental or monetary. You would do good to test on some unimportant pieces first.

Two things to consider are time and strength. That is, you will need to dilute the solution and/or limit the time a coin is exposed to it. There is a fine line between fixing a perceived problem and irreversibly ruining a coin. You can cross that line before you ever see it.

Personally, I am not a fan of the stuff. Sure, in the right experienced hands it can do wonders, but too often I have seen the damage it can do.
