Vintage 1959 Silver Roosevelt Dime Necklace with fine silver tone chain

This is a 1959 Silver Roosevelt dime set as a pendant. The dime is 90% silver (0.0723 Troy oz of .999 silver). It is part of an estate jewelry collection that spans the 1930s-2000s. I’ve marked that chain as “silver tone” since I don’t see a mark on it saying pure silver. The chain has a broken link at top which can be repaired or the chain can be replaced.
