As someone with 46 red hat tokens and far too many other tokens too I hate tokens for fashion.
I cannot sell those tokens as nobody wants them, I cannot sell to shop as you could with some older fashion, the new fashion seems permanent so why would anyone rush to buy it? At least 40+ red hunter hats would be sell-able now but tokens never will be.
At least make fashion event only so it might be worth buying some to save or just scrap tokens all together for seasonal chest obtained fashion again...preferably as sunlit was with a vendor (event only not permanent) and only black and white from chests.
Maybe your server is different, but last time I bought chests, about 6 weeks ago, I had no great problem selling tokens on Balor. Had 10 red fashion tokens among others. Put all common colour tokens in AH start 5k buy 6k and they all went in a week. Only thing I done was to check what was currently for sale and wait until no-one was selling the same before I put that item in AH. It was actually the rarer colour tokens that took longer to sell.
I realise now you've allowed your collection to mount up you will risk flooding the market if you try to sell all at once. But with patience and trickling things through, my own experience would suggest that the tokens would sell for a fair price.
