Eaton "American Coin and Currency" (500+) piece jigsaw puzzle. Circular puzzle 20 1/4" in diameter. I did take the time to put the puzzle together and it is all there. Nice puzzle in excellent shape with only a touch of wear. Many of the pieces are peculiar shaped (last photo). Pieces come together tight, especially as the puzzle progresses towards completion. Fun and tough. 1975. Box shows light wear. One lid corner is weak.
