I guess it is a personal pref as you say. I have tried posting many ways and the reserve does better for me. I don't have an answer as to why. I think it is just the fun of bidding for many. I have sold over 50 chips in the past 2 weeks and prior weeks with no reserve brought nothing. ????????? As long as you bid what you feel it is worth to you, you are out nothing even if you don't win. I see there are some chips out there by other sellers with no reserve so take a look at those. List a few yourself it is free.
