@hu5kers77 I don't think there was a distinction in the counting process after the coins were released. If I recall, there were 50,000 1991 libertad 5 piece sets. The fractionals all have the same lettering as the 1 oz piece (OnZa instead of onza). My guess is there are about 50,000 of the T2 1 oz coin.
@ilikeikes here is a list of the varieties I have been able to put together...
BU 1 oz
1982 DD
1982 TDO (NON COMPETITIVE?)
1987 DD (easily identified by the doubling of the decimal before the purity)
1988 DD (same as 87, though apparently much rarer--just discovered recently)
1990 PL (Do we consider this a variety, or just a lucky strike?)
1991 T2 type font is OnZa (as opposed to onza)
1999 Mule (reverse of 2000)
Proof 1oz
1983
DDO1983 TDO
1987 Plain Edge
1987 Lettered Edge
1987 Missing Feather (under Angel's left wing, viewer's right) Lettered Edge
1989 999 (no decimal in purity)
1989 .999 (decimal in purity)
(Does anyone know which one is more rare?)
(There is supposed to be a proof 1991 with 7 dots on mound, but according to Don Bailey, no known specimens exist.)
2004 Die Crack in Base
2015 2oz detached wing
