Beware if you see offered on Proxibid or receive in a consignment a Peace dollar with so-called “monster” rainbow colors. Almost always these are artificially toned.
Here is a recent example of a Proxibid auction offering a Peace dollar with “colorful toning.” (Click to expand photo.)
This is clearly a chemically colored Peace dollar.
The silver in Peace dollars has different metal properties than Morgan dollars or even Silver Eagles and therefore doesn’t easily tone. Some Peace dollars do have magnificent toning because they were slabbed by green-labeled PCI [whose holder reacts with silver], kept for decades in envelopes, or exposed to environments containing sulfur.
This is how a toned Peace dollar should look:
Note the blue, magenta and gold colors fading seamlessly into each other at the rim. Even relatively common grades like this in toned Peace dollars can be worth hundreds. Our advice is to offer or bid on rainbowed Peace dollars slabbed by reputable companies.
