How often do these raffles ever materialise, and look how long it would take if it ever got done.
My opinion or advise if you like is to have a sit down, have a think about your situation (only you know how your fixed) Decide if you really want to get rid or not, then decide on the lowest you will let it go for, reason im say the lowest is its just cutting to the chase no bullshit, if for talk sake 5k is your absolute best then advertise it for 5k strictly no offers etc etc.. I know you will have guys that will offer you a grand less than your asking, but trouble is if you ad on that grand to your asking price it causes guys to just skip over your ad as it dont stand out to them... So decide what you have to get to sell, advertise it at that and if it dont sell then keep it..
I dont really buy into the whole thing of they will be sought after in future theory, they still wont get anymore than current prices so its holding onto something for no reason imo
