I don't play for loot, I play for fun, but here is the loot I have gained since I started MVM.
I will only note loot that is substantial. (of considerable importance, size, or worth.)

Tour #28 - Strange Australium Force-A-Nature - $38.99 on marketplace.tf
Tour #35 - Strange Australium Knife - $42.00 on marketplace.tf
Professional Killstreak Knife Kit Fabricator - $21.99 on marketplace.tf
Specialized Sniper Rifle Kit Fabricator - $2.99 on marketplace.tf

Strange Killstreak Carbonado Botkiller Flame Thrower - $2.69 on marketplace.tf

Strange Gold Botkiller Minigun - $0.90 on marketplace.tf

Just never play these tours.

Never play MVM for the loot, you will always lose money.
If you are playing it for loot, don't play it, just buy the australiums, it will be a lot cheaper.
The profit is a little bit more, because I left out the lower worth items.
