According to my 1960 Blue Book, it was worth $35 in UNC, but in those days, toning was considered tarnish and not sought after. MS64 - $20
Probably 20 something in 1978. I remember paying way less than $30 for Morgans in the late seventies.
That is an MS-63 that got a color bump to 64. As I understand it, colorful toning was not widely sought after in the 70's. So, you probably paid a shockingly low price for it.
I’m stuck between AU-58 and MS 62. But I don’t really collect Morgan’s and a blind chimp could grade better.
I'm guessing PCGS graded this MS64 or MS64+ (depending on when it was put into the holder, since plus grades are relatively new). I'd imagine you picked it up for ~$15 back in the day
