Storing Old Stock Certificates - Scripophily

I had been collecting these off and on for the past 5 years or so and now I have a stack of a few hundred. How are people storing their certificates?

I'm thinking of purchasing legal size thick acid free sheet protectors and a binder to store them, but still not sure if that is the best.

A binder and page protectors would certainly work as one solution, however the binders can get very heavy and storage can often be a problem.

I'm a big fan of storing my oversized philatelic materials in these ITOYA Art Profolio's typically sold by hobby shops such as AC Moore, Michael's, Hobby Lobby, etc., and with 40% or 50% discount coupons usually available on their respective websites, the price can't be beat. Many different sizes are offered, too, for almost any application you'd need, plus they are all promoted as being ligin free and acid free, so they should be safe for long term storage of virtually any paper items:
