Bruce MacPhersonMy take on the sets I have completed or nearly so
e93: None - Pastorius was my most difficult, but several examples have shown up in the last year.
e96: Fierce competition on the popular cards (Herzog, Mack), but none stand out as the most difficult.
e97: The ones Bob mentioned plus the obvious Sullivan cards
e98: Coombs, Vaughn and Tenney - no surprises there, but I followed this set very closely for years and I believe Vaughn may be the toughest. Oddly it was my first e98 and was acquired from the esteemed Marquette collection.
e102: The typical four variations, with Doyle (bat) being the one I have seen the least.
e104-1: Lapp, Baker and Strunk; not sure if they are more difficult, but I can't seem to find them.
