storing my coins

[Fr45h3R]

My understanding is that the cardboard in Dansco supreme albums contains sulphur and this will affect coins over time.  I got rid of mine because of this.  I've seen many very high grade pre-decimal coins with this type of toning.  It tends to be black and blue around the edge.

Thanks for the heads up, i'll just pick myself up a heat sealer then and stick with the mylar flips in albums from Purple Penny!
