This is a GREAT topic! Yep, I too have the check-the-change bug! Haven't come across anything lately.
I have in the past, thru banks and retailers, distributed hundreds and hundreds of wheaties in hopes of furthering the collecting bug, but heard nothing from anyone about where did these come from or a "hey look what I found". Wouldn't it be nice if we all would cash in, so to speak, our older unwanted or inexpensive coins in this manner to perhaps garner more interest in our hobby?
I have cans, boxes and bags of wheaties and am going to use them. Maybe these thousands will attract some attention and get someone else interested in coin collecting. Yes, I have checked each one (probably two or three times for the goodies) but there are quite a few in the teens on up with most being in the 40's & 50's.
