I did a bit of poking around when this thread 1st came out.
Didn't really find much, other than there were a couple eBay listings for the Somalia back in 2011 & 2012(?), from what I recall.
That, and the currency value on both of them seem to "make sense," compared to some of the other issues by those two countries around that year.
Anyway, that's both the blessing & the curse of rare / unknown coins: Typically can't find much about 'em!
I know what that's like sometimes (for Ag), heh. Can be frustrating, especially when trying to determine approximate value. Heck, even just a mintage would be nice.
Very cool coins!
And I'm with the other poster: Try contacting the mint. Though don't hold your breath, either.
Just explain who you are & what the situation is. May or may not get a decent response.
Good luck, and let us know!
