Suriname - 25 Cent 1989 edge

Dear all,

I've noticed that some of the 1989, 25 cents coins from Suriname have different edges. (Link)

See the image below for more information. I've stacked 6 on top of eachother, the two top ones are different from the rest.



Is this something that should be added to the coins page?




Kind regards
Mike

Maybe the top two coins were minted elsewhere to the bottom five coins ... your link says that coins without a mint mark were struck at British Royal Mint while those with a mint mark in Utrecht, Netherlands.
