LOL - right now loose GR ponies seem rarer than MOC ones.

That's because of the awfully big lot of MOC that was made/is being made available to collectors through certain Greek sellers, which is also the reason (convenient for buyers ;)) why their price and value dropped significantly.
Greeks used to be among the rarest and most expensive ponies. They aren't eactly cheap yet, but that's nothing compared to what they'd go for in the past. The babies and the Greek exclusive sitting ponies
do still go for high prices.
I'm ponderig whether I should open my 4 MOCs or not, and keep them loose and able to join the rest of my Greek herd (collector ponies). I don't really collect MOCs... =/
