When Resorts announced this promotion, it was also meant to be a contest. A different chip was given away each week and you had to have a reasonably high amount of play to even qualify to get a chip.
Those at a lower level received an adhesive decal which was placed into a collectors album album. A similar album was given out for the chips.
The idea was that those who completed a set were eligible for a drawing at the end of the promotion and the top prize for decals was a five figure amount (don't remember if it was 25 or 50k) and for the chips it was, I think 100k.

They even set up a trader website so people could help each other complete these sets. Some days they had 2 chip days and towards the end they were a bit more liberal giving away chips trying to have more people complete sets.
Those that looked at outright purchasing these chips were paying from $5-15 for even the easily obtainable years and that was then.

The total amount of chips given away is not known but it is my understanding that quite a few of these chips were never given out and now gather dust in some warehouse.

They announced a drawing date along with a party and your admission was a completed set. BTW, just to throw this in, no one ever completed a decal set.
In anycase when you entered the party, they took your set and gave you a receipt and an entry for the prize. Once the drawing was over, you could reclaim you set. Many were just abandoned and perhaps thrown out.

A lot of the dates you are looking for especially 1981 and 1983 were among the real tough ones to get and truthfully, with these missing, I doubt that there are few if any complete sets out there in view of this and that is before we even get into the Joker chip.

The joker chip was redeemable for $250 cash so I doubt that anyone kept one to begin with.
Short of that, I do have a complete set (less the joker) but don't have extras of any of the ones you are looking for.

I wish you luck finding them
