Up for auction today is this set of Studded Leather Blacksmith Gloves of Mining. Each pair adds +3 to Mining and do not wear out. The set is for one of each hue, as they come in all 8 non-iron ore hues. Included here and likely the main weight of the sale is the single pair of +5 Ringmail Blacksmith Gloves of Mining. Auction Details: Minimum Bid: 25,000g Bid Increments: 1,000g or higher Buy-out: None Reserve: None Auction Close: 24 Hours after the most recent high bid has been placed Disclaimer: For the sake of any potential buyers, there is a posted bug/issue with the gloves. It would seem they only impact smelting of ore presently and do not actually give you legitimate bonuses to actual mining. http://uorforum.com/threads/gloves-of-mining.4063/
Realized I'm an idiot today. You can just take any pair of leather mining gloves, and dye them with a leather dye tub. I assume the same goes for the studded ones. So it's really just the ringmail gloves that you need to actually "collect" the set of.
