Coin Holders

As already mentioned you really can't beat an album with plastic slides and both sides of the coins are visible. They are made by Whitman, Dansco, Littleton and several others. Naturally they are more expesive but well worth it when you see the final results. Whitman Albums, as an example, can be purchased as quarter albums and you have the ability to add or remove pages. Most are similar. They look like books, can be put in a book case, prevent kids from constantly touching the coins, coins will not fall out, are easy to add new coins and so much more. 2x2's, plastic pages that hold 20, fit into a common 3 ring notebook binder but look like a school project. Air tights will make your kids loose interest as a general rule. Very young kids can and will change interest as fast as possible and anything that is to difficult is quickly dissmissed.
Please note that any of the binder or folder type setups for those quarters do not allow both sides to be seen, require a great effort to insert into the slot which means a nice big thumb print on the coin, occationally coins are pushed right through. Glue on the back of the slots also effects the coins.
