sol.
i'm talking strictly from a collectable market, the fact that there were the fewest ontarios made would tell me they are the rarest to find. I think, of my 20 or so, I have 1 or 2 ontarios, 4-5 san marinos and a bunch of ranchos. it may be a niche market, but they still, In my mind have the highest collectable value.
thats why i wanted to trade for one a week or so back
