How much should I sell my weatherbeeta horse rug for?

Its a weatherbeeta winter rug, 5 6", its very warm and heavy and only been used for one winter, just needs a wash.
What do you think a fair price to sell it for would be?
Answers:
If it just has a little dust and hair on it, probably 50% of price paid. However if it has caked on dirt or fading which may not be removable unless a professional cleans it then 30%. If it has any tears then perhaps 20% of the orig price.

Anything that still looks reasonable and has little wear should go for around 50% of new price, I would advertise it at a little over that, so the buyer can beat you down on price and think that they have a bargain. If you are not going to get it cleaned before you advertise then you need to come down by the price of a proffesional clean.
