On Coaster-Count, I've got 72 10-point coasters on the rare credits list, meaning that a maximum of 1 other person has ridden. It's a lot of kiddy crap and there are a few on there which won't be on there for long.
Without going through the whole list, Everland's Jet Coaster, Siam Park City's Loop the Loop and Superland Israel's Loop 2000 will always be 10 pointers since they've been removed, plus all the coasters at Seoul Dreamland, which closed years before any enthusiasts got over to South Korea.
