Wow - thanks for the great tip ! I know that I have some of those around - probably in my "junk" drawer (my dh marvels at all the little things I save that may come in handy some day !!) Our 2 oldest dd's have gone through all the pennies in their piggybanks and have sorted out all the pre-1982 pennies to use at the penny-press machines. They can't wait to get a book and start their collection --- in 31 days !!!
