I will agree with you to a point, In todays business model they are there to give the least and make the most, but there actually is a difference when you go to your local coin dealer or pawn shop.
Your right about trying to trade in a coin that is rare or not, they will give you usually 2.00 under spot.
But when it comes to something, like a 1oz buffalo or sunshine mint, maple leaf vs a American Eagle, they will give MORE for the eagle than any other 1oz coin.
Sometimes a lot less than spot price for something like a 1oz Buffalo.
I've been to many here in Florida and that's how they deal. Not saying it's the same everywhere.
But when you look on eBay you can see that you can buy many different type bullion for less than the cost of a silver eagle, which really don't make sense since a maple leaf actually has more silver.
Unless it's really rare and they know it's a hell of a deal, they will offer 2.00 under spot OR LESS.
Bottom line is if everything went belly up, and the coin dealer was the only persons left buying, they may give a lot less than spot price, I would want to find out who they are selling to.
Either way , I still say silver is the most undervalued asset you can own right now.
I don't care what the price is under 20.00, I say buy what you can afford , but buy.
When it does go up and it will... the hell with spot price, you will be greatly rewarded.
On that point, it was a very good video thanks for sharing.
