Again – here are the coins as they arrived from Lee.
And the star of the group on arrival appears to be this wreathed cross:
Results after the night of soaking and a bit of scrubbing – Step one on the Experiment page.
In addition to the cross and wreath, there is another showing a diadem and is slowly coming into view.
This group was then just doing the room temperature soak in distilled water for three days. They were cleaned and not much changed. They were returned to the distilled water for two weeks with a cleaning in between and still no significant change, however, the brown “crusty” pictured partially above and in the next picture up where it is right next to the dime, did develop two small chips where the “concrete” like texture is not as thick!
