2009 Virgin Islands Washington Quarter error/trial/experimental? 0

[Screeb741]

i found this 2009 washington quarter about 4 or 5 years ago and have a serious issue with it and i was wondering if anyone would have the same issue. I dont remember the exact weight of the quarter as it is now slabbed in a pcgs holder and was sent in as a possible variety when i knew almost nothing about coins. This quarter shows absolutely no copper around the edge it looks as if it is a silver quarter but i do remember that it didnt weigh out as such i believe it was lighter. It got a ms 65 grade from pcgs but was wondering if you guys think i should send it in as a mint error or possible experimental planchet or something, your thoughts are welcome please help.

Sometimes the "sandwich" of the copper-nickel layers covers up the copper core around the edge. I've seen it before.
