Ok. I can't reveal the letters of course because of an on going negotiation. However, I did try to say they were all good letters, like BR (these are not the real ones of course).
Thanks for everyone's comments. I did try the namebio thing, but that included the sales of C0 and CC which inflate the average a lot. Maybe I go over there again with my calculator and see if I can get the average without those 2.
OK. Just done the math. Without CO and CC, the average is $2917. I think this is still on the high side because the population is small and it includes a lot of country abbreviations which sold at $3000.
