Not naive, but being respectful and giving the benefit of the doubt. My first reaction was similar to yours, but crazier things have happened...Spark
If you are the EBAY seller offering this coin, you should end the auction immediately. It is a damaged coin, being sold with intent to deceive people. Has been reported !!! We don't like rip off artists (scumbags) here, preying on the uninformed.
This crap kills this hobby. Some people have NO INTEGRITY and clearly have issues if they are willing to screw someone out of a measly $150. Unreal. Man up! Stop with the garbage. Go get a job and EARN your money. But dont listen to me some random person....listen to Karma who is your new best friend.....
Unfortunately, some uneducated soul made a bid. Its a shame that buyers on Ebay can’t be warned before spending their hard earned money on crap.
The mintmark from 1946-1964 was on the reverse bottom, left side of the torch. Since 1968 it is on the obverse above the date. There are no 1938 Roosevelt dimes, those are Winged Liberty, or Mercury dimes. Your coin is 100% 1988-D worth 10 cents. Nice trollery though.
