Out of interest, I bought what was touted as a Freeman 129 in the December 2013 LCA. It's a lovely coin, but after careful examining, and taking account of information from other sources, I don't think it's a proof, but I'm confident it is a specimen strike. In a conversation with Martin Platt about this on facebook a couple of years back, and he too doesn't think it's a true "proof", which he highlights as nearly always having a thicker than normal rim. Moreover, interestingly, when listing the late Roland Harris collection, Gouby disagrees that two of his three 1889 proofs, were in fact proofs - not sure whether 129's or not, as Gouby has his own unique method of classification, and no Freeman equivalent is given on those pages.
Anyway, here's the coin I bought as a Freeman 129, Lot No 2166:-
Reverse
Obverse
