I got 2.4 troy ounces of silver Japanese Sen coins today. The 10 Sen coins are from the Meiji reign (late 1800's-early 1900's) and those ones are 80% silver and the 50 Sen coins are from the Taisho reign (early to mid 20's) and they are 72%. All together i got about 1.75 troy ounces of pure silver for only $35 leafbucks or in other words at around 40% of spot.
