Winterspring Rugged Leather Farming Location (Classic - WoTLK)
There are a few different plus sides to this farming location. One of them is not only do the yetis drop silver they can also be skinned which will greatly increase your overall profit here. While skinning here you'll see lots of rugged and thick leather which can sell on the Auction House for quite a bit depending on your server. As Horde the Rugged Leather is used in the Venomhide Ravasaur questline in Un'goro Crater, so it will be prone to sell for more on this faction.
Another upside to farming here is the amount of yetis there are for you to kill. Combining the outside yetis and the ones inside the caves there are probably over 100 here. This means at pretty much any level you can clear the camp and by the time you're done the first bit is respawning. Also it means there is room for more than one person, if by chance someone else was here. The yetis also drop humanoid-like grey items such as grey pieces of armor, weapons and also food/drink. Either way between the skinning and raw coin you will be making a good amount of money here.
