So I have been into collecting for like 8 months now and I have a little less then 500 books (until Christmas... :) and I have them all bagged and boarded. I bag all of my comics in the general bags (polysomethingorother lol) and I have recently read that they can wear down after a certain amount of time, so you need to change them. I have heard numbers of 3-5, 5-7, and 7-10 years per change. I looked into harder and found out about mylar bags and want to know people's experiences with them and roughly how much they cost because they can be expensive, and if they really work as well as they are supposed. If I get a good backing I might slowly switch my comics to mylar.
Oh and let me know what type you use... such as mylite 2 or 4 or the weird combo ones (forgot their name).
All help is welcomed and happy collecting and reading to all,
P.S.- If I don't post a thread or blog again this month, Happy Holidays to my Comic Book Brethren
