As mentioned on this forum many times, I like to use Heritage for historical pricing info - not just their auctions but current prices as well.
I understand where they get their PCGS, PCGS+, and Numismedia Retail prices(those are all readily available from their respective websites and I am very familiar with them). But where do they get their "Numismedia wholesale","Numismedia NGC (nmn)" - whatever that means, and "Numismedia PCGS(nmp)" - again what the heck is that?
These numbers are far lower than the others - and more in line with what I target paying for coins. Their origin would be interesting - are they also available online somewhere?
So many coins at Heritage are gem+ that I can't identify AU and lower prices there for a lot of coins, so I'd like to find their source - if free and online that is!
Thanks in advance!
