I've never really been much of a souvenir collector.
Yes, I have thousands of books, but I don't consider then to be souvenirs. In 2008, I finally had a couple of extra bucks,
and I endulged myself and got a couple Robbins medallions.
The Robbins medallions are one of the few semi-official sovenirs of the space program.
Robbins medallions are a souvenir or memento made available for NASA astronauts when they are scheduled for a space flight
which are personalized for the specific mission they represent. These medallions were produced in both sterling silver
and 14 karat gold however the gold ones are much more expensive and because of the low amount that were made they are actually quite rare.
