Hello Everyone!

I am back to arranging my coins!
But I am having trouble determining the differences in these:

-1955 DD penny and 1972 DD. Where is the double die shown?
-1970 S small and large date, what/where is the difference?
-1979 S Type I and Type II, What is this?
-all of the 1982 varities, ????
-1983 DD rev, on what part?
-1995 DD obv, on what part?

If you know of a site where I can study it and maybe see a picture, it would be most helpful.

Thanks!

The date.

It took me 7 months to pull the whole 1982 variation set from circulation.
