The three Caymans  have "limited self government."  This means that they can do
whatever they want as regards their internal affairs subject to the provision that the
British appointed governor has veto power on anything he doesn't like.  They have nice
convenient extra-private banking disclosure laws there, a good deal for those whose

 Coinage commenced in 1972.  Prior to that Jamaican coins were used.  The
circulation minors have had the same reverse types since their inception.  1972 and '73
coins are most commonly found Unc wholesale items, particularly 1 and 5.  '70s dated
25 with ship reverse have been moderately common in the poundage I've come across in
the last couple of years.  I have not found 1978 Jubilee commemoratives in lots, though
the same items in sets are not uncommon.  With the exception of the 1987 1 the new
"mature portrait" coins have not been stocked extensively by wholesalers.
 On to the precious metal NCLTs.  There are only a few I'd really consider
common.  These are the $2 and $5 coins of 1973, '74, and '75.  Others that occur with
moderate frequency are the 1972 Silver Anniversary $25 of 1972 and the 1986 Sports $5.
The "Queens" $50 of 1975 is also a fairly common piece, not too expensive considering
its high face value.  The rest of the commemoratives, I'm sorry to say, are fairly scarce
and have to be sought out.
