Toughest "Common" Capped Bust Half Dollars

This is a "cheat sheet" compilation of the R1, R2, and R3 Overton Varieties that are diffictult to obtain in higher grades, or even at all. Info is based on a variety of sources combined into a compilation and counts only the last 10 years. I did this because any common coin should be making regular appearances on the market, and not showing up infrequently like many R4 or better varieties do. Any problem coins are not included, as I believe most are interested in problem free common varieties. The info below may not reflect actual rarity, but then again it may. For example, if someone is having an impossible time finding a decent example of an R2 (500-1000 examples known), it may be that the variety heavily circulated and most are in VF and lower grades, and the few higher grades are already held in collections. On the other hand, the particular variety may actually be more scarce than the published information indicates. The below info is based only on AU and MS appearances in major dealers and auctions.

I will be possibly adding more info to this over time as needed, and attempting to update the list as these varieties appear on the market.

I mention the O-102 do to the XXX edge demand and only 1 MS O-102 XXX appearance, along with a relatively thin POP of AU coins.
