1922/1 overdate threepence - dud or real ?

[echidna]

This one looks dodgy to me.
The doubling does not look right for starters.
And the surfaces don't look original...
What do you reckon ?

I can see the two 1922/1 die identification markers quite clearly. There is widespread strike doubling. I don't know how common that is on 1922/1 as it would not be visible on lower grade examples.
It looks Ok to me.

Compared to the two I have in my collection, it looks OK to me.

There is a lump above the roos knee and that is found on genuine coins. The seller is legitimate (he is a Dr IIRC and I have made a number of purchases of him).
The surfaces are lifeless (dipped?), so are most of the overdates out there.

Can you elaborate on what they are for me?
(Neal has mentioned the lump above knee).

These are the two marks that are found on all 1922/1 overdate threepences.
This image of a genuine coin is from the Nobles archive.
