I don't know that anyone who isn't a participant in a Set Registry can fully understand or appreciate what those of us who are, go through. By way of analogy: Now that a part of one of the "greatest-ever" compilations, the Bob R. Simpson collection, has been dispersed to the four corners of the Earth, seemingly never to be reunited again, imagine the resolve, discipline and dedication required to reassemble that collection again. As one seller texted me after I made an ultimately unsuccessful bid to acquire a coin at a more moderate price: "How badly do you want it?" The appeal of a Set Registry is setting a goal for one's self and following it through to completion, however long it takes, whatever the cost, irrespective of motive.
[That being said, if anyone knows the present whereabouts of a 1903 French 20-franc gold rooster grading MS-64, or better, I'd be very much obliged.]
