Don't Lose Them

We have a collection of marbles.  These marbles are the "special ones" and if the grandkids want to see them they must look at them while sitting at the table.  At one point we had 100s of marbles in a big container in the playroom - but, it seems over the years the supply has diminished (most into the vacuum cleaner) and under furniture in the basement.

Oh no - hope that doesn't mean we're losing our marbles?!?  Ok - that's pretty bad, but it's early morning.
