Thanks scopru! Glad to see you back...
Ok take a deep breath everyone...
George VI 1946 set..2 Annas
2 Annas = 22.3 x 25.5mm..5.8gr..Edge Plain..Cupro-Nickel..KM#542
Here is one of my examples..

There were 2 types of reverse used..See details below..

There were 2 types of Obverse used ..See details below..

Mintage.See details below..
Bombay....52,500,000..Mintmark 2 raised dots either side of date..
Calcutta..67,276,000..No mintmark..
Lahore....25,480,000..No mintmark..

OK...First here is my example of the 2 Annas Bombay mint..
Obverse Type 1
Reverse Type 2
You can also see in the right field of the obverse 2 diamond control marks...

Next my examples of the 2 Annas Calcutta/Lahore mint...
Note..Distinguishing between the Calcutta and Lahore mint!!
I've been researching this dilemma for a while now...Most references state that the only way you can differentiate between the Calcutta and Lahore mints is via the small diamond control marks generally found in various locations on the coin I've checked a lot of these coins and the control marks don't seem to be consistent and so I must admit I'm not really taken by this idea..Yet we have 3 very distinctive types here, and my personal opinion is this..
Bombay.....Obverse Type 1..Reverse Type 2 (Raised dots either side of date)
Calcutta...Obverse Type 1..Reverse Type 2 No mintmark
Lahore.....Obverse Type 1..Reverse Type 1 No mintmark
This also sits well with the mintage numbers, Bombay and Calcutta using the same reverse type 2 (Very easy to find) Whereas the Lahore with its lower mintage using a type 1 reverse (Slightly less on the market)..Any thoughts welcomed?
Coin 1..Obverse Type 1..Reverse Type 2 Calcutta ?
Coin 2..Obverse Type 1..Reverse Type 1 Lahore ?

There is one coin variation that is quite rare that I luckily acquired for a few bucks recently (Seller obviously didn't know what it was)...Difficult to find..
Calcutta...Obverse Type 2...Reverse Type 2
Obverse...Incuse wings in each corner..Crown touching 'N'.....
