Verification please :)

Hi All

i need help with verification of those coins 

Purchased with other hammered coins which I have no problem but those 3 coins makes me confused 

all 3 are silver coins 

1. 1.6g 2.2mm with two dates on

2. 3g 2.1mm

3. 2.5g 2.3mm

All coins have remove/cut off rim and look strange for me 

any help please:)

Top left is probably this:

N#52445 

I believe the reason for the strange edge is that they have been clipped, had material removed and sold so that they could get extra money out of pocket change. The other two are shillings, (XII in left and right fields) don’t know what monarchs though.

Hi I managed to find out all coins in catalog but one have two date on 

strange as never seen anything like this 

one date is in place where should it be and second date in 90^ on a left side 

and clues please?

Probably double struck, hammering coins wasn’t always a perfect process so I could definently believe that the workers forgot to exchange the struck coin for a blank planchet.
