I posted yesterday about a cleaned 1909S peso that I bought for $20. With a relatively common coin and low cost, I figured I may as well try to artificially tone it for kicks and giggles. Before: Classically over-cleaned, a dull shine with no character. Method: I hard boiled an egg, and mashed it with a fork. I put it in a container with the coin over to the side, making sure not to make contact between the egg and the coin. I left it in for around an hour or so. Results: I left this in wayyy too long. I could have just been content with the edge toning I saw in the first 20 minutes, but then I actually forgot about this, went back to work, and suddenly remembered about my egg coin. I feel like this went a little too extra, but either way more attractive than the original toned version. The reverse toned up much better than the obverse, for whatever reason - I like the blues on the edge; the obverse didn't really get much fancy color. Conclusion: Egg-and-tuna salad sandwich for breakfast!
