I have a large box of crown-sized silver coins, mostly late 20th century. I rarely look at them because they are safely stored away in a safe deposit box. I've had them for around 7-10 years. I decided to go through them recently and was shocked at the sizeable increase in catalog value for almost all of them. I had recorded the CV at the time I bought them and not updated it since. Now I know that CV is not the same as market value, but I would assume that the percentage increase in the two is somewhat similar. Is this a fair reflection on the potential increase in resale value? What is your experience of general price increase for large sterling silver pieces since the 2008 recession? I am talking about coins which require a 2.5x2.5 holder and are in the range of 0.57 to 1.4 ounces of silver.
When were the "catalogs" you're using to look up "values" compiled and printed? Silver dipped below $10/oz in late 2008, and soared into the 30s and 40s just a few years later. Those changes may well have swamped any changes in actual numismatic value.
All were taken from the current version of Numismaster at the time I bought the coin or the current value as of last week. I am aware of the price fluctuations. The lowest I bought silver at was about $9.80 spot (I paid around $11.50 with premium if I remember correctly.) and the highest I sold at was $47.50.
