you are lucky! (it definately says 1992 right?) cos i thought i'd found a few once but they were 1996... Oh the irony, now if i had been looking for a 1996... They do turn up occasionally, if the mintage figures are precise then exactly 1% would mean that of the rarer type there are 1,291,743 of them in existence, but the mintage was much less than 1% according to Tony Clayton's site, which means that there could be less than 1 million minted, which means they are a good deal scarcer than many predecimal coins of George V's reign, and scarcer than even some Edward VII coins. The other scarce variant of 1992 10p, with the L and I pointing between dots, and the 1 in 10 also between dots, with broad flat milling are quite scarce, also less than 1% of the mintage. more info see... http://www.tclayton.demon.co.uk/dec5.html (anyone got a 1992 mint set [not proof] so that we can ascertain which type is in there, i'm thinking L I between dots and 1 in 10 at dot.
