I have this White Negress token from England and it has some funk on the reverse, I think it might be glue but I'm not certain what it is. Also, at around 5 o'clock on the reverse, it looks like there may be some rust starting to come to fruition. I've tried distilled water, acetone, and MS70 all to no avail, I even tried Verdi-Care just for good measure. I mean it looks a little better than before but definitely not good enough. I'm thinking about trying Mint State Restoration, there's pics below of the Token and the MSR. Has anyone tried this MSR on such a project, any suggestions? Comments appreciated!
