Spot the Difference if you Can #15

Recently I got a call from a customer who was entering some Great Britain Machin stamps and he was questioning the value of one of the stamps in our EzStamp database. This collector had 27 copies of a particular stamp valued at about $20 mint & $11 used. He was doubting that he could be so lucky. Upon discussing it further with him, I determined he had misidentified the stamps.
There are four 10p stamps that are quite similar and can be difficult to identify properly.
The four stamps are Scott # MH69, MH70, MH70D  & MH71.
They all have the same perforations & print method (Photogravure ).
So whats the difference? The differences lie in the zero of the 10p denomination and subtle colour differences as shown below

10p Machin Head Types

 One of the two GB 10p Machin stamps compared, EzStamp MH69 — brown-red Queen's head with "10p" at lower left.

Great Britain 10p Machin stamp in orange-brown, EzStamp MH70, Queen's head effigy facing left.

Orange-brown Great Britain 10p definitive, one of the Machin stamps compared here — EzStamp MH70D

Great Britain 10p Machin stamp MH71 — orange-brown Queen's head in profile, value "10p" at lower left.

Look carefully and you can find these varieties. It turns out that this collector has 25 copies on MH69, 1 copy of MH71 & luckily 1 copy of MH70D worth about $20 !
The detailed differences are listed and imaged in EzStamp. Check your collection and see if you have any of these varieties

Happy hunting.
