I generally pay well over spot for semi-numis but they tend to be more stable in the silver market. For example if you pay $65 for a privy mark Kook & the price of silver drops to $25.00 the coin will still be worth $65.00 due to it's numismatic value. If your a bullion stacker you'll get hit by the spot price reduction immediately. Something I have noticed recently is the obvious upward price trend on ebay. I don't often buy from there but it's interesting to see a trend developing. It's common to see people bidding well over spot for silver lately. One ounce bullion bar around $45 plus freight. What kind of customer is willing to pay these prices ?
Here's a perfect example.
