I didn't know it was rust when I bought it, I thought it was old scotch tape but I was wrong! I've tried acetone and MS70, the acetone took much of the brown away and now it's a blueish color. I have a bottle of Mint State Restoration, but I'm leery to use it! Any ideas? If I use the MSR, how long do I let it soak for? The prices on these white negress Tokens has gone way up, take a look at feebay and you'll see! Here's a couple of pics, in hand it don't look too bad but pics show everything!
