Coin albums work great for date and mint-mark collections but make sure they are made of materials that won't damage your coins. Most albums are now acid-free. Some, like Intercept Shield and Dansco Supreme albums feature inserts or slipcovers to defend against the elements. Albums store well on bookshelves, display both sides of each coin, and feature attractive pages with pre-printed dates. Those dates and pre-cut openings however, are also inflexible constraints.
My ideal would be a set of trays with openings flexible enough to hold raw coins, capsules, certified slabs and 2x2s. I'd give up the ability to see both sides of the coins if I could easily turn them over. While I'm asking I'd like to print my own labels for each opening and for each tray. Anybody know of such a coin collection storage and display system?
