Irish coin verification [solved]

hi everyone 

I just got a coin and struggling with verification 

Any help appreciated 

I thin this is a Irish coin but not sure 

one side has crown and letters CR under the crown 

other side has number 3 in the center 

 What is the diameter? 

Cannot see the 3 number. 

Some lettering   CAR   MUM   AUE   perhaps. 

20mm and there is definitely no 3 on second pic:)

 Now that I have cropped them, I now see 

a thistle (and 71 below it) on second picture. 

So rather than Irish it may be Scottish. 

[20mm] 

 So CR may be Charles Rex and may be one of these two 

N#43965 [20 mm] 

N#63398 [19 mm] 

 May be that first link, as top right of 

the CR are the II letters - for Charles the Second. 

Obverse: Crowned 'C R II'

Lettering: CAR D  G SCOT ANG FRA ET HIB R 

Translation: Charles, by the Grace of God, King of Scotland, England, France and Ireland 

Reverse: Thistle

Lettering: NEMO ME IMPVNE LACESSET 

Translation: No-one shall hurt me with impunity 

 I have made a request and uploaded brighter pictures for that page. 

CAR D  G SCOT ANG FRA ET HIB R / C R II 

NEMO ME IMPVNE LACESSET 

Hi Zac You are a start:) 

After see pic from link this coin is Charles 1 one as had no 1 on right side of the crown 

And you was right, there is no no 3 but over the years it looks like:)
