The public reacted negatively to it. They ended up back on the obverse at the base of the bust in 1918.
Oddly coincidental, I found a 1909-S a couple of weeks ago metal detecting but I couldn't for the life of me get a VDB to grow on that reverse... :-) (still worth about $50-$75 though!). One of my forum associates got an 1909-S V.D.B. in Vallejo earlier in the summer, one of the perks of west coast detecting is you get a LOT of -S mintmarks and they are often the tough ones.
Now I gotta go look through my 50 or so Wheat Pennies.
