Are The Margins On These Stamps Normal...?

Hi guys..Take a look at these Mint Scott 736 Russian stamps..Those borders, are they normal..?

Probably for the Russians they are.

Looks like a selvedge imprint. Like some other countries, they used to do this in the good old days.

These are " marginal rule " lines, it was used to reduce pressure on the edges of the printing plate and so obtain clearer and better production.

British collectors will know them as "Jubilee Lines" first used with QV prints in 1887

Evidenced in a lot of countries stamps.

When the line is unbroken, it is referred to as "continuous", when broken "Co-extensive"

Yours are co extensive marginal rule lines.

India, co extensive marginal rule lines, pin punched twice, for what reason?
possibly to identify the plate.

Is that what Jubilee Lines are for, learn something new everyday....

Here's a Polish infla Postage Due pair from 1923

That's right YeaPolska,
your "Jubilee line" is on the right, broad blue
looks "continuous"
Strengthens the printing plate.

Here is an example of such a line with a Dutch Indies stamp from 1948.



Same stamp/series with a pretty big margin at the underside of the sheet.

The Indonesian stamps were printed in photogravure by G. Kolff&Co - sheet-fed with cylinders that possibly were in fact curved plates - where the edges joined there may have been a split that gained ink ....!?
