I've never bought any of these rounds, but mercury dimes are my absolute favorite and I once pulled 40 out of one box of dimes when coin roll hunting, that was my best score. Part of the reason I like this so much is due to the design, but they are also the perfect weight for barter and no one will question them when trading, because I fear that some of the survivors of the zombie apocalypse won't know that pre-1964 Roosevelts are 90% silver.
