Westwood, you never answered previously about this... Where have seen you seen/heard that this hoard was out of Bolivia? In that NGC thread about these, someone mentioned hearing something about a hoard out of Colombia (nothing concrete)...
Jfransch, it appears Westwood had previously posted what look to be correct cumulative pop numbers for what seem to be the correct, common assayer/crown type combos (with appropriate Krause KM#)
As per Krause, here's the breakdown for 1754, the transition year from two "Royal" style crowns on the pillars (KM 104.1) to Imperial crown left and Royal crown right (KM 104.2). The prices are from my slightly older edition, just given to display relative rarity at the time:
KM #104.1 - Royal crown on both pillars:
1754/3 MF -- $55 in VG up to $325 in XF
1754 MF -- $50 in VG up to $250 in XF
1754 MM/MF -- $300 in VG up to $3,500 in XF
1754 MM -- $300 in VG up to $3,500 in XF
KM #104.2 - Imperial crown on left pillar, Royal crown on right pillar:
1754 MF -- $150 in VG up to $950 in XF
1754 MM -- $60 in VG up to $375 in XF
From auction archives,
ebay, and various forum postings, I've identified several sequences of NGC submissions that were apparently from this hoard... These consist of mainly Mexico 8R dated 1754, but also some Mex 8R from the years immediately preceding that. Most of the 1754 Mexico pieces seem to be "1754MO MF MEXICO KM-104.1" and "1754MO MM MEXICO KM-104.2"... I also note one "1754/3MO MF MEXICO KM-104.1" within one sequence. I don't find any of the scarce to rare (per Krause prices) 1754 Mexico crown/assayer combos in those number ranges. In addition to the Mexico pieces, there are a number of 1754 and 1755 LIMA mint pillar 8R, as well.

http://coins.ha.com/c/item.zx?saleN...&lotNo=22489http://www.ngccoin.com/certlookup/C...=1525042-___001-008 are all 1754 LIMA mint UNC 8R (incl. one 1754/3), 009 and 010 are 1755 Lima, and just one, 011 is Mexico. If those are indeed from that same hoard as the groupings of all Mexico pieces, that lends some credence to the idea of it being a hoard surfacing from South America rather than Mexico.
