That is a beautiful 1st year Seated Dime. I dug the same year but mine is in VG
grade. At least an XF for you and also worth about $550, figuring with the scratches on the edge maybe half that but no less that 200 bucks. Tell your dealer to cough it up 80 dollars you better find a new coin shop that will give you at least 200 and that is bottom dollar even, but I guess they have to make a living to that guy you went to seems like he wants a retirement plan
I am a coin dealer by the way so if I could sell it I would buy in that range I told you. I'm not just some guy talking make sure that you know what you have before you walk in those places. I wouldn't take less than $200 your getting raped if you do.
