Silver Medals Of Unknown Origin Or Purpose.

I am including two items as they are related-and came from the same collection.

Both appear to be silver, and are featureless aside from the initials on one side and what appears to be a date on the other.

The larger has the initials I. F. F, and number 19 21/10 07, which surely must be the date of 21 October 1907.

The smaller has the initials F. I. V. and the numbers 19 04/10 9=08, which surely must be the date of 4 October 1908.

The larger is 31 mm and weighs 10. 8 grams. The smaller is 22 mm and weighs 5.4 grams.

I am thinking an award or medal of some sort, but there is no indication of a reason or a country of origin, The collection has multiple examples of each type, plus a copper version of the larger one, and a different copper medal with the initials F. F. I on one side, and the words "1 sta. pris" within a wreath on the other side.
