Grenada KG6
2½d – the scarce perf 12½x13½ – forgery
The 2½d bright blue exists with perforation 12½x13½. This is rare mint and scarce used. SG list it (SG157a) at £4,500 mint and £225 used. (The common version sg157 is perf 12½ and
worth very little – cat 30p).
We were offered the rare unused one recently. It was a forgery. This forgery and a genuine used SG157a (which we have in our stock)
are shown below.

Forged side perfs Genuine
·
The shade is wrong, the blue being much lighter.
·
It appears to be line perf rather than comb perf.
·
The perf gauge is wrong – see how the side perfs
line up at the base but drift out of alignment toward the top.
·
While both Gibbons and Scott catalogues list the
side perfs as 13½ it is actually perf 13¼ (as shown in the Murray Payne KG6 Commonwealth
catalogue). This forgery is perf 13¾ at
the sides.
·
Basically is a normal cheap 2½d which has been
cut down and reperforated at the sides.
That is why the top left corner perforation shows line perf characteristics
whereas the genuine comb perfs meet neatly at the corners.
At the time of writing the genuine used one is
available for sale. Please contact us
