London coin fair

[1octav]

I will be traveling to London to attend some scientific conferences but I also plat to go to the London coin fair taking place from the 5th of June at the Holiday Inn, on Coram Street.
Because I have never been to an international coin fair and because I am fairly new to coin collecting, please give me some info / tips on how to approach such an event. Are prices negotiable? Can I get appraisals for some of my coins there... and maybe sell them to the local dealers, so that I can have money to buy other coins?
All answers are appreciated.

Hi, yeap, all the prices are negociable, not sure all the sellers will accept that, but what you got to loose ? Regarding the last part, if you are a newby in this area, to do that you need a lot of informations which you don't have it. So no recomandations for that.
