Again, I have stored the following two silver coins in pH neutral paper envelopes for approx five years - I have not noticed any change in surface coloration or toning from when I bought them. I live in the very arid SW United States that has mostly very low air humidity.
Charles I (1625-1649) Silver Half-Crown (1625)
Tower Mint (Harp), Seaby 2771, North 2207, Diameter: 35mm, Weight: 15.13gm
Charles II (1660-1685) First year (1662) issue Milled silver crown
Diameter: 40mm (initial issue large flan) Weight: 29.57gm
