Identification Of Two Penny Reds

Hiya guys, I have these two stamps which my grand-mom gave me many years back. I want to identify the plates of them. Any help is appreciated

The plate numbers are shown in the mesh on either side of the Queen's head. You should be able to see them with a magnifying glass if they aren't obscured by the postmarks.

The first one ends in a "5". A scan would help

If you can do a cropped image I maybe able to see the numbers on the edge better. One maybe plate 120 one maybe plate 101 but I need to see a better closer image of both. I specialize in QV stamps on covers in my ebay store.

Hi all, here is a better enlarged image. it says plate 125, How old is this?

Plate 125 is SG143 its date range of use is 1858- 1879. Plates were used for many years as held at various UK post office. Its a nice Queen Victoria stamp with GWR perfin. The crease in the bottom left decreases its value. There is an mourning cover on ebay UK with a plate 125 dated 1870. Seller is asking £19 for that (over priced). But a loose damaged copy maybe only worth a few bucks. Its got a numeral killer bars =74= cancel on your stamp.

GWR would surely stand for Great Western Railway?

The 74 postmark is from Birkenhead, 75 is from Birmingham.
