I can help you get started by linking you to a topic where a user named crydit tracked few coins that once had value but are now dead -
https://bitcointalk.org/index.php?topic=588413.0 and there's this site as well which lists coins that are probably dead
http://deadcoins.com/ (I've noticed that not all of them are dead, some of them are actually rising in price, but no idea why they're listed there.)
There's also a list of coins with low value which you may have to manually go through over here:
https://cryptocoincharts.info/coins/info/101-to-1000. Like for example DATA (an altcoin) had a higher value but dropped later -
