I know the MS70/PR70 market is huge in North America, with companies sending 1oz bullion coins and to grading companies en masse in the hopes of an MS70/MS69 grade. But what about the MTT? Since they're still being made in both regular and proof, I thought that there would be at least a few that had been slabbed in ultrahigh grades. Is it because American interest in MTTs is low, and nobody else cares about MS70 coins? Or is it because they aren't sold in bulk (as far as I notice anyway), and so you can't send in thousands to get graded?
