My 3 year old son Jacob has enjoyed cutting coins with me since he was 20 months old.  Since the creation of my "numismatic jigsaw puzzles", my son loves saying "cuttin' a puzzle dad".  His cuts are pretty straight with occasional turns.  Even his 5 and 6 piece puzzles are hard to match up because all the edges are the same.  So I turned his idea into reallity.  Just as in the picture, square edges, and no interlocking pieces make this style much more dificult.  Add this option to your shopping cart with any puzzle and I'll cut it more difficult like in the picture.  Can you count the 21 pieces in that picture?  "Numismatic Jigsaw Puzzles" is an original idea of Jeremy Barrett and copyright of Coin Cut Art; DBA Home Base Marketing.  All patent rights are reserved..
