I am sure with over the years of collecting I am into the thousands of ounces.
I have not bought to stack tho, neither gold or silver, just have been collecting the coins I like.
In the past 3 years tho, my collecting has slowed down, on purpose as I started seeing prices coming down due to the spot market.
I have really pulled in each year, and really have concentrated and made an exception for my Somalian elephants, tho even there I have pulled in. As an example, I have refused to buy a Kilo elephant coin and have ignored gold somalian elephant coins.
The main reason being that the downtrend in silver and gold has brought the prices down of those coins and thats too much to put into a coin when I know it will either be cheaper once the slide is over... and if not, then I would rather buy as prices finally break the downtrend and start to go higher. The other reason was dealers such as MCM not pricing their coins even remotely close to spot price.
But no, I was not buying coins at the top, a big major portion of my collection was when prices were rising early early early and I continued to buy.
Its been a long run in some aspects.
