I'd offer you a trade-in value for those if you wanted to trade + cash for the R1 sharkskinz I've got for sale...
OEM fairings for late model bikes in MINT condition are generally worth around $800 - $1200 on ebay for the full set + lights. Obviously some sets have sold for more and less, but thats seems to be a pretty good average. When light damage comes into play, I think it just depends on who you sell them to. In general it will probably knock a good amount off the resale value as a set, but to the right person in the right situation they might still be worth a nice penny.
