Thanks for the response and info. In general, my coin inventory (that I'm selling) includes the following:

I'm located in Arizona (Phoenix area).
On a related note, I believe the coins graded by David Hall and IGA were graded in the 1980s. Back then, did the grading scale generally stop at MS-65? I wonder if some of the coins labeled as MS-65 may be a higher grade using today's scale. For example, see below for the 1943-S Mercury Dime that was given a grade of MS-65.
Thanks.
