Even ugly coins need a good home and who knows, maybe the album will brown up the coin to something nice.
For me, if I don't want it to tone, it will tone in about 3 weeks. If I want it to tone, it will take about 5 years. Oh well. P.S.--Great buy sweetz!
I would guess it would depend on the album, the storage conditions and the cleaning of the coin. So I can't really answer that question.
