Still using the Krause online catalog (wont get my book until Christmas) so bear with me.
Hong Kong 10 cents (1961, 1963, 1965) varieties 28.1 and 28.2 both descriptions and metal (nickel brass) were labeled the same...what is the difference?
Hong Kong $1 (1960) varieties 31.1 and 31.2 also labeled as the same (metal copper nickel).
The difference is the coin's edge. KM# 28.1 (1955-1968) has the "security edge", with an incuse line around the rim which looks kind of like two coins sandwiched together. KM# 28.2 (recorded for 1956 and 1963 only) is a mint error, with "normal" reeding instead of the security edge. KM# 28.3 is identical to KM# 28.2 ("normal" reeding) except it's not considered a mint error, as post-1970, they decided not to use the expensive security edge anymore.
The dollar is the same: KM# 31.1 is security edge, 31.2 is the erroneous "normal" reeded edge.
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
By the way, some of these coins have small KN and H mintmarks. I just realised when I got my Krause the other day, and some of the coins I thought were swaps actually had this different mintmark.
