Actually there are a couple of online sites where you can order most of them:
http://www.blaircandy.com/candy.html (under nostalgic/fun candy)
http://www.hometownfavorites.com/penny-candy.htm (where you can buy candies by the decade they were most popular or first introduced)
http://www.candywarehouse.com/nostalgic.html
http://www.nostalgiccandy.com/store/
None of these are "penny" candy anymore but would be a fun surprise for somebody celebrating a milestone birthday, complete with newspaper of the year they were born and that sort of thing.
For the heck of it, try the quiz at
