Yep! It would only hurt if they were all 1879-S MS68DMPL and you unloaded them at the same time. Chris
That is true. Selling all at one would hurt price a little but there would be ways. If I took 100 79-S morgans in 64/65 to Baltimore next week I could likely dump them all. But doing an auction this price would start to slide. I saw this on the 1881-O 64DMPL when there was 10 or 12 in one auction last year.
