While I am currently number one in my mint set (1866). It matters little, my ranked position. I choose to share the coins with this site for others to enjoy the coins I own. I look at others sets, because of descriptioins and photos. Those without are just not worth perusing.
I think very few of the Number 1 sets you see truly are #1. (Except of course Bruce AKA Tradedollarnut) Afterall to be #1 you would need every pop top coin or close to it, just to say without a doubt you are the Kahuna. I think I would be foolish to think that I have the altime finest 1866 mint set, just because NGC says so. I know there are others who have them but just don't share them. I am certain there are nicer sets.I do agree on the omission of obscured sets. What is the point if you don't share.Just my thougths..
