Temporary filling of holes in Dansco albums

It seems like Dansco (or somebody) would market discs/inserts that could be labelled to fill those spots that you have a slabbed coin or when a coin is very rare or very pricey. I have heard people using blank planchets of a particular coin, or cardboard cutouts that they labelled, or an extra coin (sometimes with the reverse showing). I would buy a pack of hole-fillers that included various sizes and labels to put in my dansco if they were available. Probably not enough of a market for something like that, but would be kinda of nice to have.

1. Go to a hobby store and purchase a sheet of colored plastic. Just make sure it is of a Mylar type. Cut to suite.
2. Go to almost any flea market or coin store. See if you can find a pile of cheap foreign coins and use them to fill the holes.
3.Go to a hardware store and purchase Copper Washers of a size that will fit. Being Copper they will stand out and not be confused with a coin. Some have Brass washers and they shine better too.
4. Not sure if they still carry those but a place called Harbor Frieght used to sell an assortment of Copper Washers. If so, order them and use for those fillers.
5. Or use Stainless Steel, Tinned or Zinc plated washers.
6. Fill the empty slots with a cotton ball
7. Pour concrete into the slots. Problem then would be how to get it out later.
8. Send incompleted Albums to me and stop worrying about those empty slots.

You can use P and D mint tokens to fill holes in cents albums. Perfect fit.

I actually like the empty slots in the dansco albums.
They give you the incentive to hunt for the coin needed to fill the hole/holes
if they really annoy you just write down what is missing and only open the album when you fill a gap

Have any of you thought of scrapbooking sheets? These are relatively inexpensive on sale at stores like Michael's, and because scrapbooking materials come in contact with very sensitive items (namely: photographs), they are acid-free. In a scrapbooking context, this is to prevent colour transfer, fading, and blotches--you can see how this translates to coins. Also, scrapbooking sheets come in many colours and also in patterned pages--you can get whatever colour you like, cut it to size, and boom, there are your markers!
