I believe attic find has become a term much like garage sale that encompasses more than what is spelled out in the name. That said a lot of old houses have secure attics but leaky basements so storing things for decades Undamaged is far more likely in the attic of a home than the basement. Attics are also less accessible generally and as people age they are less likely to go into attics and root around etc therefore things getting lost in them for decades especially in homes passed down through the same family. So I do believe an attic is a far more likely place to find vintage collections hidden away in trunks or old boxes or drawers.
