Photo (Scanned at 1200 dpi) attached is of a cover of mine that has six #134's, five of which I clearly see grills on, plus a 136 also with grill. I need another set of eyes to look at the third from the left 134 and tell me if you see a grill there (the stamp with the really dark almost SON cancel).
Second question: my Scotts (2004) lists 134 w/grill on cover at $185. What's the current value, and how would you value multiples like this?
EDIT: third question: is this something that should be authenticated / certified?
And oh, yeah, of course, if these AREN'T 134's please tell me and give me an idea of where I went wrong.
Thanks in advance for all your help!
