Wow tough crowd, I guess I'll play the devil advocate on this one, let's look at the gold panda market for a second. Based solely on eBay Supply, it is extremely tight and limited meaning hardly anything is coming up for auction, and whatever is up for sale as BIN is IMHO speculative and unrealistic pricing for the most part (in today's value). So the Gold panda market has basically come to a holt, which is weeding out many people that are looking to buy/invest/collect pandas.
Now here we have the silver panda, which is made with as far as I know the most affordable precious metal besides copper. Which has many uses, industrial and medical and much much more. Now you include reasons why people purchase these coin, (investments, collections, and one of the least talked about reasons gifts!.) Me personally I give away at least 5 silver pandas every year, examples: graduation, birthdays, and Christmas. And for all those that don't know there's an actual gift market of Precious metal coins/medals in China mainly around the time of Chinese New Years, and my understanding is those coins do not come back to the market.
Now let's look at the global demographic of the silver panda buyers, the continents I would consider the most influential are Asia, North America, Europe, and Australia.
The rough combined population is 5.5 billion. You'ld be surprised how a market with strong demand can absorb even a large mintage number like the 2014 silver panda. So you see 8 million really isn't that large of a number when you put it in perspective. I remember in 2011 when the mintage number jumped from 800,000 to 3million, people were crying and complaining, why such high mintage numbers, the markets ruined and flooded! I just ran a search for the 2011 silver panda and only 54 listings came up, compared to hundred back then. Who's to say next year they won't make 15 or 20 million.
So in the end I have to disagree with you guys, they can be a good investment as Jay shows in his charts, and the fact that silver is at a four year low makes you really think about the long term potential. Silver has broke the $45 dollar mark twice in the past who's to say it won't happen again.(someone wise once said history tends to repeat itself)
Full disclosure: I have know relations to Jay or the China mint or anyone even selling silver pandas. In fact I have only a hand full of older date silver pandas. I'm just a collector out of Phoenix Az who enjoys reading and learning about the different MCC sectors.
