Two-Fifths (2/5) Oz.
The two-fifths ounce 2008 $20 specie was released alongside the 1/5 oz. and 1/10 ounce in early 2008 in anticipation of an increase in silver prices. The naked back was stamped with a surprising number of hallmarks, many of which can be seen below. There may be additional variations, if you have pictures please send to brian 'at' norfed 'dot' info and I will credit you here.
