I Have A Two Penny Blue Perfins

I have never seen these on the internet. Are they valuable?

This is, I think, Plate 15 - dealer price around £5 in good condition. This one's too badly damaged to have any value. Perfins tend to reduce value, rather than increase it.

AS said by GeoffHa, your stamp is a plate 15 Twopenny blue.
It is an S.G.47 (Scott#30), printed in 1876, and has the perfin of J T Morton based in Milwall and London who were preserved provisions manufacturers. Of very little value due to condition but keep it as an example of that perfin.

1st I really like the stamp, 2nd try to recall the moment when you wanted & dreamed of a bicycle.... so this is the thing I want to know (like the bike) very nice answer, my compliments

Thanks guys! :) Perfins really reduces value? :O

Not in all circumstances. GB perfin stamps began around 1868 so early examples would be reasonably valuable as well as collectable. Your perfin stamp dates from 1876 so is into the times of greater usage so is not uncommon.
The condition of your actual stamp if it were un-perfinned would make it worth very little but, although the perfin is not uncommon, it would be worthy of keeping as an example but the value would be quite low too.

Thanks
