Dumb as an old medallion to the thumb - a coin isn't exactly a medallion, but this one is so worn that it's dumb to the thumb, though it certainly tells a story. The date on the coin is 1817 - I found it with some old family stuff with dates in the late 1800's, so I imagine that's when it was found and put aside.
The other medal was my great grandfather's, and taking the photo has inspired me to do some research. I always wondered how come it says Boston on the front, but the inscription on the back with the date is Killarney, in the southwest here. As far as I can make out it must have been from a major Irish literary and cultural festival. You can see the old Irish script, which was pretty much phased out by the time I was learning the language.
