I have some quarters (1965 thru 1989) in a Dansco that have turned a soft orange/gold color.
Does toning have a natural progression of color?
If I leave them in the album, will the color contine to turn and how will it progress?
If I take them out of the album, will the continue to turn?
If they are dipped in acetone, will that stop any further toning?
Thanks
