Q: I have a collection of 200 to 300 California and Bordeaux reds from the 1970s thru mid-1980s, including first- and second-growths, Heitz Martha's, Mondavi, BV, Diamond Creek, etc., and would like to sell most of it. I have been away from collecting for well over a decade and do not know who the reputable auction houses and retailers are. How do I assemble such a list? -- Mike Dolan
