Shouldn't even be that hard. Maybe even have a use for a 100 POINT system.
PCGS and NGC (others too for that matter) could collate their pop reports and sort the database by number.
That would give a relatively accurate estimate of number of extant specimens of coin types.
Actually even dates within the series.
Then, on a percentile scale, coin types could be designated by percentile rarity.
I think a lot of changes would evolve in pricing once it was seen how disparate price is from rarity.
People could take a coin and KNOW that it was rarer than 80% of all other types.
Comprehensive and useful.
I think.
Collectors could further rank by condition ..inside... the type. Or date.
What think? The math should already be done on the counting. A new database could be no more than a cut and paste job.
A long time ago, I totaled mintages in a Coin Prices book. But mintage is not the determinant for extant specimens.
Whattya think? Wanna vote?

If coin A had 1000 graded
and Coin B had 500 graded
Then coin B would be known AT A GLANCE to be twice as rare as coin A.
Taken to the ENTIRE range of types, the reader would know that some types are ENORMOUSLY rarer than more EXPENSIVE coins.
And he could do whatever he wanted.
Even nothing.
Wasn't thinking of putting on a slab. A publication. Book.
And notations would be advisable on more modern issues.
Even maybe a "not enough data yet" on non classics.
<< <i>Pop reports can not be ufed to accurately judge rarity. >>
Okay. What can? We aren't talking EXACT numbers. A percentile scale can be soft in data.
