Hello guys, I got a question, I like to collect currency but I want to know that if i keep my currency in those currency pages that are 100% pure prolar polyester and that could fit three bills on each page do i still need to put each bill on another individualy plastic before I store them in these pages in my binder? The store that I purchased them from said they are good to place the bills on. but they never told me that i needed to place them in another plastic. Thanks for any info.
