Will513 Posted November 6, 2019 Share Posted November 6, 2019 (edited) Hello I'm new here, can anyone tell me why, my 1921 PEACE DOLLAR is toned brown? None of the rest are this color, I even have a 1928 that is darkly toned but it's not this color/brown!

Greenstang Posted November 6, 2019 Share Posted November 6, 2019 Welcome to the Forum Will That is just toning that has changed to a darker colour. The next stage is that it will turn to black. I have a couple of silver coins that have changed completely black. Link to comment Share on other sites More sharing options...
VKurtB Posted November 6, 2019 Share Posted November 6, 2019 (edited) They probably were once "dipped" to brighten them and the dip was not properly neutralized (baking soda bath, then distilled water, then acetone) before storing them. I'm a photo geek and Agfa once made a "silver stabilizer" chemical called Sistan, which I used on my classic black and white prints and negatives, and those treated with it are really still high quality. I've bathed some silver coins in it, on the theory it will stabilize them against "turning". Edited November 6, 2019 by VKurtB Link to comment Share on other sites More sharing options...
