To me, a 131-card set does not provide the greatest value for future resale, since you're talking about one-complete set and an extra half-complete set With a 131-card master set, you'd only be 37 cards short on another complete OS2 set. So why not just get two full-complete 84-card sets? That's exactly what I did--all glossy backs, and without consideration for astericks. Here's how I did it.
Original Series 2 (Version 1)
40 cards featuring the Leaky Lindsay/Messy Tessie puzzle back variation.
#49b is Schizo Fran
#46a, #46b, #47a, #47b have the name Schizo Fran identified as card #49b on the checklist
#42a, #42b have the Spaz Award on the back.
40 cards with the Live Mike/Jolted Joel puzzle back variation.
#49b is Fran Fran
#46a, #46b, #47a, #47b have the name Fran Fran identified as card #49b on the back
#42a, #42b have the Sneak Award on the back
*1st set has Leaky Lindsay puzzle, Schizo Fran Checklists, Spaz/Sneak Awards, and both versions of #49b (Schizo Fran and Fran Fran).
*2nd set has Live Mike puzzle, Fran Fran Checklists, Spaz/Sneak Awards, and both versions of #49b (Schizo Fran and Fran Fran).
Many people try to make this an 86-card set with both back variations for #42 Patty Putty/Muggin' Megan, but without regard to the Schizo Fran/Fran Fran name variation (an 85-card set). I think that at a minimum, it's more important to include the name variation for #49b (Schizo Fran/Fran Fran), than to include the back variations for #42a/b (Spaz/Sneak Award). Including the variations for both #42a/b and for #49b will make an 87-card set. That's what I've done for now--two 87-card sets for 174 total cards.
