Gold Dueling Badge
From TF2 Wiki
The Gold Dueling Badge is a level 3 Miscellaneous badge released as part of the Mann-Conomy Update. It appears as a gold, rectangular badge which is displayed on the chest. The medal is awarded after a player has reached level 50 with the Silver Dueling Badge, and its level increases by 1 for every 10 duels won by the player. Once the badge reaches level 75 (740 wins) it is upgraded to the Platinum Dueling Badge.
The badge also displays win percentage based on all duels played, and the time, date, outcome, and opponent in your last duel.
If the badge is deleted, a new one will be awarded upon completing another duel. This new badge will have the same stats as the old one, but a new "date received".
- Not including random drops or being challenged by other players (but including the 5 rewarded dueling games for every 10 wins), the lowest possible amount of money a player can spend on the Dueling Mini-Game in order to get this badge would be $48.51 (48.51€, £28.91), which buys 245 duels (49 sets of 5). This is assuming each duel is won.
- Unlike the bronze badge, when you complete enough duels for the gold badge, there is no "#PlayerName has earned Gold Dueling Badge" message broadcast to the server. This also happens for the Silver and Platinum badges.
