The medal's obverse bears head of Native American in feathered head-dress facing left.
The reverse bears two leafy stalks flanking legend: SOUVENIR / PENNY / (star) / OF / BOSTON
This is a very large and beautiful "penny" about which I know next to nothing. The "Indian Head" pennies were struck until 1909 and had a design very similar to this on their obverse. There seems to be a wide variety of these Indian Head souvenir medals that pair the beautiful bust on the obverse with different inscriptions or designs on the reverse. Any information on these medals would be appreciated.
The circular medal measures 74.5mm in diameter and appears to have been cast in a base medal and possibly silver-plated.
