it depends.
>sanforized
no way to tell if they're uncuffed.
>unsanforized
you can usually tell if jeans are unsanforized without a cuff and nearly all unsanforized jeans are selvedge.
if one of the legs twists around like this they're unsanforized. you can tell without the cuff. the direction of the twist and what leg it shows up depends on the direction of the twill weave of the particular jeans.
the crotch area will often times skew along with the leg twist, so a \ shaped fly is another sign.
some unsanforized jeans will not have the leg twist because they haven't been washed, and some manufacturers counter-skew their jeans to to counter the twist.
or if the denim has a hairy texture to it they're unsanforized. hard to explain but you'd know it if you've seen it. the jeans will reflect light less, look more matte and striking to the eye from a distance.
pretty much all unsanforized jeans are selvedge. other than a few exceptions like a niche fabric ih does and some vintage stuff like lee's old half selvedge.
oh and here's one more exception to the rule: a lot of vintage jeans without any visible selvedge id are selvedge. old western jeans tended to use a double felled outseam for comfort on the saddle + strength and nobody really cared about the selvedge id back then. so the jeans were selvedge and made on a shuttle loom but they just cut the self-edge of the fabric off and threw it in the trash or used it somewhere rolled up into a seam where it isn't visible.
