Larry and Barry, if you keep an eye on the printed (value side) you should notice the print disappearing within a month, until it's all gone.
I keep my extras in post card slips and use "SAFE-T" Stocksheets for my collection. The designation is 4B for four slips per side of the page making a total of eight tickets per page. There is five pages per packet at about a dollar per page. They also have three silps per side for a total of six per page. These are sold at Stamp stores. I haven't had any fading since I stopped using the currency pages. Since I had so many currency pages, I started collecting foreign currency too.
