Never really understood plate proofs Tony,
how many of them would be floating around?
So the printer or the engraver prints some impressions
on card, I would have thought only a few would have been archived
from those requiring an example.
Why would you perforate a plate proof?
Of course, I just live in Australia - I don't collect it - so I can't give an authoritative answer.
How many floating around? Can't be many, if Gibbons rates them £1500 a pop. When was the last time you saw one on offer? It would be a fair guess that there was only ever one sheet.
The
why of plate proofs is fairly simple. The printers need to check the impressions from the whole plate. Then, they might want to try the impressions on different types of stock, and the client might want to see the effect of different colours - so more plate proof sheets printed.
Why perforate the sheet? Who knows? Perhaps it was a trial run on the 1/-, which proved unsatisfactory. (Something to do with the chalk-surfaced paper making perforating with the 13½x12½ machine difficult?) Then, who knows? Maybe a normal sheet was spoiled, and the plate proof sheet was handy and was substituted. AFAIK, there isn't any suggestion of funny business associated with the stamp.
To an
Indian States collector, it all seems perfectly reasonable and feasible
