I ordered some for an overseas customer of mine. My order was processed quickly and the silver was shipped promptly. The 10 oz stacker bars are very nice.
they guy who got me into PM's lives in scottsdale and raves by them. i think their 10 oz bars stack and have serial numbers.
they are not well known where i live, and their prices rival JM/Engelhardt without the corresponding liquidity/name recognition.
However, I've noticed that the Scottsdale Stackers carry a higher resale premium than other bullion on ebay though. That's usually my best indicator for market demand with more than 15,000 silver bullion listings at any given time, it's a good way of keeping tabs on the market.
Also will note that JM/Englehard are generally the brands that get knocked off. Engle is bankrupt (so no longer producing) and JM doesn't make new retail size bars anymore. So if you want NEWLY minted bullion in these names, out of luck.
Old Silver bull market vs Today's silver bull -- and personal preference of course.
