Oh, they're definately worth less, how much probably depends on scarity. If you're talking about one of those early ERB All-Storys it's probably not a big deal as they're really rare in any condition. If it's a more common pulp like a later WT then it's more of a problem. That said, many of Jerry Weist pulps were described as trimmed, but yet people bid on them as though they were untrimmed. I was shocked at some of the prices realized for those trimmed pulps. I have to wonder if some people didn't read the descriptions well enough. Was yours disclosed as trimmed? I think I got the one WT that wasn't trimmed---lots of overhang.
