Scott #9 is specifically classified as Type IV. It is defined by having at least one outer line at the top or bottom rec

Interesting points

1) Plate IV (#9) is derived solely from plate I late (reconstruction). This plate was recut in May 1852, the first stamp from this plate being issued on June 1st, 1852.
2) 199 positions of the 200 on the plate were recut and many, if not all, were re-entered (the exception being 4R1L which remained as a type II (Scott #7). Any pair containing position 41RL are extremely collectable, I have not seen one in auction records for the last decade.
3) 113 positions on plate 1 had both the top and bottom lines recut, 40 positions had only the top line recut, 8 positions had only the bottom line recut, 11 positions had a double line recut at the bottom and 4 at the top and 2 positions had a double line recut at both the top and bottom.
4) Stamps with the double recuts (see note #3) are worth more than those with just one recut.
5) There are numerous double transfers, and a few triple transfers, none of which command high prices.

How to read plate positions

The first indicator is a number indicates its position on the plate, so 3RIE would have come from the third stamp on the plate. The number can range from 1 to 100, there being 100 stamps on each plate.

The second indicator is either the letter R or L, R indicates the stamp came from the right pane, L for the left pane. The stamp was printed in sheets of 200, each sheet was further divided into two panes of 100. Hence 3RIE would have come from the right pane as the second indicator in 3R1E is the letter R.

The third indicator can be from numbers I (1) to XII (12). This indicator is always shown in roman numerals. There were twelve plates, there are no stamps from plate VI (6) as it was destroyed before printing began (no doubt it was flawed). For example stamp 4RIL would have come from plate one (1).

The last or fourth indicator is either the letter E or L. The letter 'E' indicate an early state of the plate, the letter 'L' indicates the late state of the plate. This indicator only applies to PLATE I, as it is the only one that has an early and late plate. The early plate is the original plate. After 11 months the plate became worn and 199 of the 200 positions were recut. 113 positions on the plate had both top and bottom lines recut, 40 positions had only the top line recut, 8 positions had only the bottom line recut, 11 positions had a double recut at the bottom and 4 positions had a double recut at the top.

How many plates were there?

There were twelve plates of the 1¢ Franklin made, plate six was never used, probably due to it being damaged in it's creation. Most of the plates were used for both the imperforate and perforated design. Some only produced one type or the other. For instance, plate 12 produced only perforated stamps and the early state of Plate 1 produced only imperforate stamps whilst plate I late (reconstruction) produced both imperforate and perforated stamps. Plate 4 was the last of the imperforate plates to be used.
