Bag of mining gloves. Leather +1 and Studded +3. Winner gets entire bag S/B: 1gp Last bid to stand 24 hours wins.
made some calculations... 1 pair of leather gloves gives back 1 leather piece, 1 pair of studded gloves - 4 leather pieces. If we assume that leather/studded gloves are 50/50 - then it's 125*(4+1)/2 = 312 leather pieces. If we count leather price for 20gp - then it's 312*20= 6240 gp. So if you plan to use it as a resource for leather - you are overpaying
I don't get your math. There are 3 leather gloves (+1 mining) and 4 studded (+3 mining) shown in the pic.
