There is a good rule to follow when collecting rouletted stamps: Don’t
I apologise to collectors of classic Finland, but I am sure they will understand why I say that. Rouletting, whether of the fancy Finnish kind or the regular straight cut kind, may be all right for raffle tickets, cloakroom tickets, printed on thin paper without gum and where only rough separation is needed. But for small size stamps on paper thickened by gum, rouletting does not work.
Here are some of the problems we have inherited:
1. Post office clerks who tried and failed to separate rouletted stamps cleanly often gave up and started to use scissors. Many classic rouletted issues were supposed to be an improvement on previous imperforate stamps, but the clerks decided otherwise. This creates confusion now because some rouletted stamps will look like imperforate ones thanks to what the clerks did at the time.
2. Collectors in the past thought that the rouletted stamps they were soaking off covers looked untidy, so they tidied them up by trimming off the roulettes. Where scarce imperforate versions of the rouletted stamps existed, they sometimes cut down a rouletted stamp to produce a spacefiller and a fake imperforate. Dealers also did this and the result now is that the world is full of faked imperforate stamps which were originally rouletted stamps.
3. Though catalogues confidently give spacing sizes for roulettes ( roul 8,roul 11, and so on), it is very hard to measure roulettes unless you have a multiple which makes things easier. Indeed, if you insist on collecting roulettes, my suggestion is that you collect multiples.
South Australia is notorious for both poorly perforated and poorly rouletted stamps. It would seem that the workers who did the job had access to unlimited quantities of rum. The work was so unsatisfactory that some rouletted stamps were subsequently perforated in order to try to get a better result. Badly perforated sheets were also removed from post office stocks for overprinting to make what are known as "Departmentals", an interesting group of stamps used on Official mail.
Between 1855 and 1868, the first design for South Australian stamps appeared imperforate, rouletted, perforated, perforated over roulette, and perforated x rouletted. So a serious collector has to try to illustrate all these possibilities, as well as shades. Fortunately the watermark remains constant.
Take a look at this group of 2d stamps in a variety of shades. All have traces of roulettes even the one which looks as if it has been seriously cut down. But then ask, Which copies here are good examples of South Australian rouletting? Some are clearly better than others but compared to the kind of clarity which perforation usually permits, none of these stand out as just what a collector needs …
Most of the stamps here are almost certainly SG 25 and 26 and so have a catalogue value of only two or three pounds each. For purposes of writing this Blog post, I have washed them but would not otherwise have bothered.
