You can get your small date 1982 D cent authenticated at PCGS. It is not inexpensive.
Your best bet is to post a good photo of both sides of the coin here. Someone here will let you know if you are correct about the small date, etc.
You want good pictures of it even if you're sending it to be authenticated, just to protect your interests.
Anyway, I hope you have indeed found one. Looking forward to seeing some pics.
