Yes it is a small date 1982-P cent. Here is some info. http://www.lincolncentresource.com/smalldates/1982.html
No YouTube lol but reason was asking is I’ve got a lot of 82 pennies and found this to make sure it’s the small date before I start going though them all
The large date 2's are very sloppy, so it's easy to tell the difference. The large is also closer to the rim. The small will have a snowman shaped 8.
The pennies are zinc 2.5 and copper for the other 2. In 1982 they switched from copper to zinc towards the end of the year. As for the gold plated coins, it's considered damage. These were plated and sold as collectibles on TV coin huckster shows. They shouldn't be magnetic, but possible that something in the plating is magnetic. Face value.
