Most of these sets that were stored in any kind of humid environment have ruined coins, from that horrible red fuzz on the plastic holding tray. However, sometime the environment can be favorable, and the result is a very cool natural toning. This is probably the first bright pink to purple specimen cent I have seen (most turn blue colour in the double-cent specimen sets).
Another 1973 specimen cent, with full red lustre is also shown, to show the relative degree and colour of toning. The photo does not really do this coin justice, as to the intensity and depth of toning...
