Just read a short article by Richard Giedroyc, and he references the Numismatic Stock Index has risen since December. What is the Numismatic Stock Index? And where can it be viewed? I goggled it and came up empty handed. I found info on the PCSG3000 index, but I think that is a different index.
I believe it was Solomon Brothers who once published a coin index. But someone gave away the components by mistake so they stopped publishing it.
I assume this is the article to which you are referring ? https://www.numismaticnews.net/article/news/coin-market-at-a-glance Apparently he's a staff writer for Numismatic News - https://www.numismaticnews.net/author/richard-giedroyc But this Numismatic Stock Index, what he calls the NSI - that's something I've never heard of. Not surprising really, as I haven't been involved with Wall Street for many years now. I could be wrong, but I don't think it's a regular "Street' index either. Based on a couple of the other articles he's written - http://pcgs.nelsonme.com/?cat=16811 http://pcgs.nelsonme.com/?cat=19173 - and I'm only guessing here, the NSI seems to be something he's come up with on his own. The NSI seems to be a basket of the stocks of various numismatic companies, he refers to a few of those companies in his articles. And it seems as if he's using this "index" to have something to write about, in a positive way. I can only assume that's because the coin market as a whole has been doing but going steadily down for over 10 years now ! And if coin mags wanna stay in business - well, they aint gonna do that by telling everybody how bad things are. They've got to find some way to write about something positive - not something negative. And he's doing that with his NSI. Well, the stocks of these numismatic companies may be going up, but the value of coins sure as heck aint ! But then that's because the two things don't have anything to do with each other.
