Maybe they are trying to get you interested in numismatics? Fine gift and a great start to a collection.
My in-laws would have given me a picture of myself as number one on the FBI's most wanted list. Nice set thanks for sharing.
That's what I gave all my relatives, for their coin collections (whether they want a coin collection or not ) for Christmas last year.
I think he was meaning something like 1976 the year someone in your family was born, or the year someone got married! Very nice proof set! You're lucky to have it!! I gave two of my great nieces a birth year proof set for Christmas last year! They are great gifts IMO!!!
Yep. 1rstSgt22 nailed it. Usually, there is some significance for the giver or recipient of a proof set.
