A pair of coin silver MEDALLION napkin rings

One is just cause to raise the flag, but a pair? Splendid! These are oval, 2 1/8" X 1 3/8", and stand 1 3/4" off the table. Unmarked, but attributed by a VERY knowledgeable fellow to F.A. Durgin of St. Louis. I tried to put both in the same frame but couldn't get sufficient detail, thus the two similar looking enlargements. One has some dents of the type made by a small, sharp object on the back side, as shown in photo three . There is slight wear to the high-points. Overall, however, the effect is quite pleasing and they have a very hefty feel in the hand.
