It has been my experience that issues of The Trader Speaks from the late 1970s to the early '80s draw some interest, mainly from collectors who are trying to fill in gaps in their publication runs. I think TTS issues that are pre-1975 would be much more in demand, just because I seem to see less of those offered for sale. Regardless of the years, they're not big-ticket items. I'd venture an estimate of $5-$7 an issue for the late 1970s and a little less for ones from the '80s. Early 1970s issues, maybe $8-$10 an issue. If you've got complete years, those might be easier to sell.
My suggestion would be to post on this board a list with a breakdown of the month/year of each issue that's available. I would try selling them individually at first, then maybe offer the ones that don't sell as a discounted package. I've had very little luck selling these on eBay.
Hope this helps.
