Green Cancel, Is There A Particular Type?

I notice Scott puts a premium on Green cancels for many classic issues. Are there limited types/shapes of cancels that could be green?

Because color is so variable, my thought is to eliminate certain cancels by their type. Like the one below. Is that a shape that would have been found in green?

The circle of wedges cork cancel can be found in many colors, possibly in green. I believe that the post office required black ink
black ink cancels, but smaller post offices used what was on hand. I don't recall any specific type of fancy cancel being limited to a specific color and think that the premium for a green cancels applies for any green cancel, as it was not a common ink color, brown ink is even scarcer! Although I do know thought that circled stars were struck in green ink.

littleriverphil.....this GREEN cancel looks suspicious.
looks like the GREEN is OVER a BLACK star cancel.
My guess (looking at this scan)....FAKE. sorry.

A negitive A simalar to the circled star.

Phil,

That negative A is from Boston, not green.

As far as green cancels go, they're quite scarce and many blue cancels are mistaken for green ones.

CORRECT....
GREEN painted OVER BLACK cancel.
FAKE....sorry again

Because of the premium Scott places on them, I assumed they're scarce. Thought perhaps, they are limited to a particular post office and or style of cancel.

You said green painted over black cancel, are you referring to the top stamp, or which stamp are you referring to, I'm very confused?

Thanks

There was a recent article in the Chronicle about colored cancels on 69s.

stampmaster, I think that Kevin means that both of the "green cancels" I showed are both fake, green ink painted over black cancels.

I used to think of green cancels as something deep like a 3c Banknote. Now I have a different sense about it.

The cancel on the left in this group is blue. Though some would claim it has green in it, I don't think so. The other two are unmistakably green.

essayk;

It could be my monitor that's screwed up, but neither of those green cancels look genuine to me. In fact, I don't think I've ever seen that shade of green ink used on 19th century cancels. Are either of them certified?

While I have nowhere near Mr. Weiss' experience here, I completely agree with him. In fact, the center stamp clearly has had the cancellation added - note the black cancellation ink at UL and LR. I have had two mentors tell me to avoid that mustard-yellow/olive-green color as it is not authentic.

littleriverphil - The two painted green cancels sure do make an excellent addition to your reference collection.

Hmmmm. I don't recall who sold me the one in the middle, but I got the 2c with the star from Rich Drews back when he still had his store. I suppose I should send it in to be sure.

Yes, they are both suspect. Is there any bleed-through from either of them? Kollectorkurt makes a strong point about the black cancel traces on the middle stamp, and the ink color on both is very close, which is also suspicios.
