I think the most is right around $100 so far. SS Satin n Lace, Lightning and the Sunbright, Berrytown and Meadowsweet dads were in that range. They were all close to mint. I haven't spent more than that for a pony yet, but I am sure at some point I will. I did spend $200 on a MIB Lady Lovely Locks doll. Mostly because I got in a bidding war with someone and I am sure I paid more than I needed to.
