These have been out for about 20 days and still have no price. The Genuine Glenngarry Bonnet and Genuine Brigade Helm, Which are also part of this promotion were released in january. The Bonnets starting price was 8 keys : http://backpack.tf/vote/id/510cc6f8ba2536e116000001 The price has of course dropped in the last 6 months. The genuine Brigade Helm started at 8-10 keys: http://backpack.tf/vote/id/510d9730ba2536a848000001 Price has also fallen. I understand those prices don't carry over to different hats. With the limited history on the Respectless rubber glove I thought the Bonnet and Helm info might be useful seeing as they are part of a similar promo. The minimal closed successfull trades ranging from 5- 9 keys. I'm suggesting a starting value of 5-6 keys.
