I have taken some M&M containers and Mint Containers I got from an online craft store when I sold StampinUp and created some container labels for the kids for their pressed pennies. In each container I have 2 quarters, 1 penny repeated (we did 10 sets for each kid which cost us $20 in quarters) then I have little tins I just created labels on photo shop that say _____'s souvenirs and those are to collect all their little squished pennies. I plan on having a little baggie of quarters for the odd quarter squish but we are planning to stick with pennies for cheap souvenirs! My kids love coins, and love the ones we brought back from Disney World for them on our last vacation. I think they will really enjoy this!
