Quarry Contest Hint #2

Well, no one got it correct on the first guess and honestly if you did I would be checking my house for listening equipment.

I did want to clarify one thing before giving you the next hint.  If you publicize my contest and provide me with the link, you get one EXTRA guess at any time.  Call it a rollover guess, if you will.  Example, if blogger A plugs today, then blogger A can guess twice today or once today and twice on a future day for how ever long the contest lasts.

Enough confusion, let's get back to the contest

HINT #2: The year the set was made begins with a 19.

HINT #1

Probably still not enough to easily guess, but it should help all but one of you that guessed sets from the 2000s.
Good luck and guessing is now reset.
