I purchased silver and gold US coins from Investment Rarities in the 1980's, over a 5 year period, so I did not make purchases all at once, and avoided short term price spikes.
As of 2011 to 2012, even with record metal prices, all the coins would be sold at a loss. Investment rarities slabbed coins back in the 1980's ( copying NGC and PCGS) and when I resubmitted coins to NGC and PCGS, all the coins purchased from Investment Rarities were overgraded, and way way overpriced!
The owner, Jim Cook deceives and misleads with all his fiscal right wing banter. Read his posts. You can't find a more sanctimonious, self righteous hypocrite, who bashes everyone outside his precious metal scam. Bottom Line, you lose when you deal with Investment Rarities.
