Quiz Winner

First I will describe the prize (picture left). You will notice that this stamp has letters in all four corners(NL). These were an early anti forgery device. The letters differ from stamp to stamp. The upper pair if present in all four corners are the reverse of the lower pair.

Further classification depends on the water mark and plate number. This has a wmk type Orb and the plate number on both sides of stamp near the top. This plate number (20) is clearly seen in the top right.

Enter the value 2½d and colour (blue) to the equation and we can ascertain the catalogue number, which is SG142. The average used catalogue price for this in 2009 collect Gibbons Stamps is now in the region of £42. I think this stamp can be described as average.
