Examples of Mint Hinged Stamps

A stamp that it is mint has no cancel on its face
See example below

A MINT HINGED STAMP HAS FULL GUM remaining

It also has a hinge or hinge mark on its back
Some examples are below


Stamp with the hinge still attached and full gum (MH)


Stamp where the hinge has been removed and no gum
This does not qualify as Mint Hinged (MH), it is classified
as Mint No Gum (MNG) and its value is decreased as a result.
It should be noted that some stamps, notably the imperforate
stamps of the 1930's came without gum.


Hinges have been used to cover up all manner of sins.
Here is an example of a hinge applied over a tear. There
are also two or three thins on this stamp. A thin is when
the paper has been pulled off the back partially, causing
the paper to be thinner at that spot. No matter how
small a thin or tear, it detracts from the value
