I have seen "reliable" sites use the $100K number and "reliable" sites use the $125K number. It's hard to know who is getting their information second-hand from whom, but here is a link to an auction of the
contract promissory note in relation to the sale
https://goldinauctions.com/LotDetail...entoryid=10213.
It appears that the $100K number is based on the fact that "The $100,000 payment was to be distributed with $25,000 in cash at the signing, plus three promissory notes each for $25,000, payable over the next several years at a rate of 6% per annum."
Again, I can't say which is correct but it wasn't a straightforward cash deal, which may have resulted in the confusion of the actual number.
