Too many arcana hats don't have a price, but still they are a high tier effect. Most low tier hats such as the timeless topper, that have arcana, the seller want around 5 to 4.5 buds http://www.tf2outpost.com/trade/19540339 http://www.tf2outpost.com/trade/23682745 http://www.tf2outpost.com/search/230546247 , but descents offers are about 4 to 3 buds http://www.tf2outpost.com/trade/23451482 . I'm not trying to get my unusual to have more value I just want a price for all arcana or rare Halloween effects. If you agree leave a thumbs up and stay awesome
