This larger size of the Chicago subway token was most likely used towards the middle of the 1900’s on the elevated railway. It’s almost identical to the smaller version that was used in earlier years. In the 2000’s after Chicago switched to the swipe card, all the tokens they had on hand were sold for scrap and melted down.
Other than the token, each necklace is made with new materials. The size of a Ball Chain necklace is 20 inches. The size of a Leather Necklace can be adjusted to as large as roughly 25 inches and down to 12 inches using the two-knot system.
