are they real coins? bailiwick of jersey silver wedding

They appear to be real. Correct weight for the 5 coins.

1972 Gold Silver Wedding

thank you . i checked diameters and is exactly same so should be real but i seen 51g only so thats why i was not sure

Obviously they would have to be analyzed for gold content to be 100% sure but being 51.9 g instead of 51.05 g (target total weight) is no reason for concern.  There is a allowable weight variation for each coin plus your scale may not be exactly correct. 

thx i fid find on internet from 2 auctions sale and it says 52g and i did xray them says 22 ct gold so i think i am saved thx again for reas me
