Sorry, Archraz, but you're looking at the crowns. This is a halfcrown - same design, except for the "2½" rather than the "5" denomination. KM# 7 in the catalogue - it doesn't have the "wagon errors" the crown does. 1894 mintage 134,000, values (in my 2004 edition) $225 in EF; $750 in Unc. I'd guess this would be worth somewhere around $500, plus or minus a hundred.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
