I agree with the findings regarding spink and DNW archive searches. What frustrates me most about Spink is that the web site telling us all how good this site is not to mention the live auction function crashing a few months ago leaving us to use Salesroom. I've found the only way to really go deep into archives for free (600euro p.a. silly money for coinarchives pro) is going to each coin company sites and go thru it manually Goldberg (weak) Hetitage (good), Stacks ( weak only lists individual catalogues) noble ( good). Spink (weak, can't handle more than one key word ! !!) Rasmussen (average) CNG ( good) . MCSearch ( reasonable and has sorting on auction date or value)
