I tend to look at a lot of the reels (6500 series) from 1972 to the 25th anniversary model in 1984.
Those tend to be the "classics" and tend to be harder to get, so that is what I concentrate on.
In 1985, (well, first in 1981) the design of the reels, as well as the inner parts changed. Quality went down, and it is about this time they switched over from making them in Sweden to making them in Asia.
If I remember, the reel you are talking about is made with the same concept/design as the rocket/C-Special reels they came out with at that time (I do have a few of these, as they are special
), so it is a bit better design than your standard 6000.
The 6500 series (rockets, CS's, and C-Specials) are more desirable from this era. You do have to remember that "Special production" does not really mean much by this time period. What it usually means is some new, special design which they flog and convince lots of people to get interested in/buy. Very few of these reels are limited production, thus they are common and usually not much worth.
If the reel is mint, unused, and all the parts are there as in the box, the right collector may give you what you paid for it.
More than likely, a collector who may have some interest would give you about $80.00 CDN (about $75.00 US. Most collectors give prices based on US dollars)
If it has been used, any sign of visible use would cut the value in half of what you originally paid, then down as the visible damage gets more severe. By this time, someone who wants to use the reel to fish would likely give you more than a true collector.
