Your price ranges are about what I'm seeing. I'm not too worried about missing out on this one and also think the winner could have bid well above $260. I mainly posted the coin to see what others thought about it.
Typical obverse PL reverse not - net grade not. Doesn't look like the picture was juiced to much to me. The auction and seller look pretty legit. Start price was 235 and only went to 260 I think if he started at a dollar it probably would have been a better price cause of the obverse pic and CAC … imho https://www.ebay.com/itm/1879-S-1-PCGS-CAC-MS-66-Looks-Semi-PL-Morgan-Silver-Dollar-/333363536599
