The best advice I can give is going on coppercoins site, and take your photos like their photos, or the best to your ability, then ask your question, heres the link to all the ddo, it also has photos http://www.coppercoins.com/lincoln/dietype.php?date=1982&die_mint=p&die_type=do&page=0
In my opinion, no, it's not a DDO. Your coin doesn't show the extra thickness on the upright of the L in liberty.
