WoW ..... i didn't realize that chips could bleed ..... been collecting for only a little more then a month. To start with, the majority of my chips are stored in 20 slot pages, with each chip placed in each slot inside a plastic flip (purchased from the local coin shop). Is it the plastic that causes the potential bleeding or is the chips safe being stored this way. What other factors can cause bleeding? Excellent question you posed Robert ... I am really learning lots from this post.
