LeeSweet Cap fact 42's usually don't command any premium over any other common back. Depending on who's looking for the back, it may bring slightly more than another common T206 back (maybe 10%). I'd say a T206 PSA 5 common with the common fact 42 sweet cap back would bring / be worth about $125, give or take a few $.
Edited to add: Piedmont factory 42 PSA = $250 with a common player on the front.
