Here's a fun little blast from the past blog!  I have been collecting these vintage coin saver bank folders back from the 50's and 60's.  At the time these were geared towards kids to teach them to save money.  (What a Great idea!)  haha    This one I'm showing today features a squirrel and he's collecting "nuts" or what I would call "Mercury Dimes"...   I wanted all of these dimes to be blast white just for the fun of it, but to my surprise while finished and sitting on a shelf I noticed that the dimes are starting to tone.  Well the top half of the dime that is...  Crazy!   The part that is slid down in the pocket is still shiny silver.  Now I would have thought it would have been the opposite perhaps the cardboard having some chemical in it...  But no, the part of the dime not touching the cardboard toned.  Any thoughts on why this happened?  Another crazy thought...  This little folder holds 30 Mercury Dimes and when filled up you have saved $3.00!  Well back in the 50's that is!   haha     Hope you enjoyed my blog!  Comments are welcomed.    ; )
