metalman and bubbatinamarion, thank you for your posts regarding this medal awarded to your relatives.
It looks like no one still has an idea about the monetary value of these medals; although, I'm sure they have great sentimental value for your families.
Considering the lack of general information, I'm going to go out on a limb and say the monetary value is probably limited. Value is, of course, determined by supply and demand. While the supply appears relatively low - one of the links above states that 500 were made - I suspect so is the demand outside of some very specialized collectors. Therefore, even if you tried selling them on eBay, you would be hard pressed to get anything significant.
Again, my opinion is based solely on generalities of the collector's market and not on specific information regarding this medal.
Hopefully, these latest posts will attract some interest among some of our experts.
