Hey Xxx, ... You ask some really good questions. Personally, I think that bullion only acts to preserve wealth, whereas Pandas have the potential to grow wealth. The best answer in my opinion depends on a few factors: What is your investment time frame, and are you after physical growth gains ? Option 1: If you're looking at a short time frame, less than 1year, and only want some quick cash gains. I think stacking bars might be a good approach. E.g. Take advantage of lowish spot prices. Pros: A quick cash gain is nice. Cons: In real terms based on silver, you have only maintained your position. E.g. You can only buy back the same number (or less) of ounces that you have sold. E.g. If we were back in 2005, and bought 100x 1oz Silver Generic bars/coins (bullion, ASEs, Maples, etc), today that would only trade for 1:1 for generic silver (or less). You would only get a cash gain, but no real physical silver gains. ... Option 2: If you're looking at a longer time frame, more than 5years, and want some real asset gains, I think stacking bullion Pandas (2011 and 2012) are a good way to go, despite their high mintage. Pros: You could actualize a cash gain, and grow your silver stack at the same time. Cons: It could take a few years to mature - or may never mature. The storage conditions of the coins are very important. E.g. Take a look at 7 years ago. If we were back in 2005, and bought 100x 1oz Silver 2005 Pandas, today that would easily trade for 200-300x 1oz Silver 2012 Pandas (and much more generic silver bullion). You would win in both cash and asset gains. E.g. Take a look at 5 years ago. If we were back in 2007, and bought 100x 1oz Silver 2007 Pandas, today that would easily trade for 150x 1oz Silver 2012 Pandas or even more (and much more generic silver). E.g. Take a look at 3 years ago. If we were back in 2009, and bought 100x 1oz Silver 2009 Pandas, today that would easily trade for 150-200x 1oz Silver 2012 Pandas or even more (and much more generic silver). Plus their are grading options and opportunities that could be worth exploring a few years down the track. Hope this helps. Kind regards, Yennus.
