Great Britain 1887 2-P - Confirmation

Simple question - it this stampworld GB1887 -1892 The 50th Anniversary of the Regency of Queen Victoria, #88?
I see such stamps offered on internet for almost nothing. Have prices gone down that much? (not saying my stamp is mint, by the way)

This is the 2d stamp from the 1887 Jubilee issue. These had a long currency, are very common and are worth pennies.

Yours appears to be SG200.

Most stamps from the reign of Queen Victoria have heavy cancellations and smudges. The IRS and the Post Office did not want their stamps to be re-used. The post office, therefore, used those heavy cancellations.

The colours of the surface printed stamps, especially in green and lilac colours, tend to run when soaked. Lilac and green were the only available double fugitive colours. The IRS liked to use double fugitive colours.

Centring also tends to be poor. This Jubilee set was the first that did not suffer from bad centring and had some colours that would not run when soaked.

So, most of these stamps in used condition are of poor quality. The high catalogue price, only, applies to stamps in perfect condition with a clean cancellation that leaves the portrait clear. A smudged appearance, heavy or oily cancellation, toning, more than one shortish perforation, or faded or run colours cause the price to fall of a cliff.

In very fine mint, especially unmounted, prices have gone up. But less than fine used are in plenty supply and remain cheap.

NSK, thanks again for clear guidance. Fascinating there were 'heavy stamping' strategies as well.
