How much are single keys worth or sets of keys?

3*3 worth about 5fg
1 key set 1-2 fg

i do stash + inventory all 3 for 5 usually

So a full torch set is worth 5 fg?

Pretty much. Organ sets can be bought generally for 3 fg, and unid torches go for 3~5 these days.

on no i do a discount, like 10 sets for 5 fg

i just have a char called keys,

and i put all 3 types in equal quantity in her stash, and her inventory, then sell them all for 5 total,

but i think im the best deal on keys here, i always sell her in a couple mins ive never really counted how many it is haha

Ok thank you for the info
