This is a string of miniature Pennies linked together. Not a real size penny but miniatures. The 1964 Pennies measure 3/8” diameter and the bracelet measures 6-1/4” long. The clasp is marked copper and closes tightly. I believe this was made in the 1970’s and has highly detailed Lincoln one cents with the front and back. In great condition. I do not see a maker’s mark. Fits about a 7-10 year olds wrist according to online size chart.
