This 1898 stamp in my collection is terribly off-center and seems to have color blotches on the right side (is there a philatelic term for that?)
But the interesting thing for me is the roulette perforations, and the catalogue possibilities of the stamp.
SG descriptions of the 1d vermillion stamp:
256 Zigzag roulette in black.
256a Zigzag roulette in green.
257 Zigzag roulette but plain.
258 Zigzag roulette in black and zigzag roulette plain.
259 Zigzag roulette plain, perf 12 1/2 by 13
260 Zigzag roulette in black, perf 12 1/2 by 13
261 Zigzag roulette in black, and zigzag roulette plain, perf 12 1/2 by 13
Scott prefers the term "serration" over "zigzag"
Question: I see no black or green in the roulette, so would the stamp pictured be 257? Not sure why a roulette would or could be given a color. I would love to know why that is. Or how it could be. Maybe the color was put down first, as a guide before cutting?
Anyway, appreciate any information on this. Cheers!

That isn't an off-centered stamp, what you have is a misplaced perforation variety, and the red blotches may have been caused by a foreign object when the ink was applied by the roller, or it was over-inked and displaced by the doctor blade when it was in the process of removing excess ink.
The term "doctor blade" is believed to be derived from the name of a blade used in conjunction with ductor rolls on letterpress presses. The term "ductor blade" eventually mutated into the term "doctor blade."
Damaged doctor blades can produce a variety of printing defects, such as railroading and railroad tracks, or continuous streaks, marks, or lines appearing on the substrate, caused by incomplete wiping of the cylinder. Such problems are commonly caused either by nicks in the doctor blade, or by dried particles of ink or other materials stuck to the rear or back of the doctor blade (described above).
So Eric, what you have is a stamp with two major varieties; quite an interesting stamp.

Robert, thank you very much for this information. Will do some research tomorrow on doctor (ductor) blades and other issues you described. Very interesting indeed.

Question, what is the difference between an off-center stamp; and one with misplaced perforations. As Einstein would say, "Is'nt it relative?"

There is a big difference between a stamp that is off-center and one that has misplaced perforations.
OFF-CENTER
An off-centered stamp is when the design has been printed too far to the edge, this stamp is centered too far to the top, this is not an error but a poorly printed issue, it is a very common printers fault and such a condition will affect the value of the stamp.
MISPLACED PERFORATION
The $1 stamp shows the perforation placed through a stamp leaving part of the stamp still attached to another stamp, and if I removed the top stamp both would look similar to Eric's stamp. This is an error caused by the paper slipping or sticking and was somehow overlooked when the sheets were proof checked.
