The set has from 1975 thru 2002 in this set. 
Many are still wrapped up with original papers, others without, but in very near excellent condition.  
1979 buckle is in extremely poor condition, worthless really but fills the group. (28 total)
 
Study the pictures carefully so you are fully aware of the condition of this buckle, and all the rest, then make your decision of its value to you.  Just so there is no misunderstanding,  buckles are sold as is, just as they were purchased originally.
