English PSA 10 graded primarily, but really anything desirable or deemed a “chase”, ranging from wotc to mid era BW/XY to modern. Even lower grade “chase” cards are seeing increases of 2x - 5x from before last November. Some desirable Japanese exclusive promos are doing quite well too, though some have barely moved as they are quite niche.
Less desirable cards have still seen modest increases of 1.5x too but that may just be more due to the increased interest. JP set cards that have an English equivalent haven’t really moved much.
