I gave it a shot to create a price guide, obviously number of public sales is too small for this to be "bell curve" accurate so this is my WAG. Thoughts?
Sketch Set Value Notes
count Size
10 250 $250 Wanderbread color $400 ebay auction was high end abberation
13 200 $250 9 to life, Hoppy Meal, Ser4 Combos, Phillies Runt, ser6 combos. Not all collectors chase combos so ser4 combos might sell for less
25 250 $200 StenchBerries/Gaggin Strips Not a lot of public sales of Stenhberries so this is best guess
30 300 $150 Lice, H8 Tough call on H8 as some may chase combo version, tomato or beet versions of it and it seems to have high appeal to collectors so they may tend to sell for higher
33 100 $200 Series 1 Cardgarys hogged the supply causing spike in prices, expect prices will come down since quantity of 33 of any other sketch doesn't fetch $200
40 200 $75 DeadnBuried, Rex, 7Pup, Molten. 7 Pup sold for higher but no reason for it to sell for more than the other equal quantity titles
40 250 $125 Wanderbread Seems to have more appeal than other qty 40 titles but expect prices to settle on this
50 250 $60 Tombs, Klepto, Speed Lick, Maulboro, Captain Moron Should be priced between the qty 40 and qty 66 titles
52 52 $150 Halloween Grouped the different classes into one group, high quantity but special appeal to these yields higher price
60 300 $50 Alpha Bytes, Killing Croc Killing Croc seems to have higher appeal so may sell for higher
66 200 $40 Series 3 Shows the number of completists out there is far below 66
83 250 $30 Series 2 Shows the number of completists out there is far below 83
