I have dealt with many dealers, each have differences in opinions.... but the most important take away is they do not care if you buy or sell, they need the trade for profit... that's all they seem to care about (with few exceptions).

I started collecting Silver coins as a child... you know when a silver dime (90% silver) was worth 10 cents, now it is about $1.20. I started collecting Gold at $500 per ounce... now $1250.

Always remember(I can only speak of US comparison), an ounce of gold was originally $20, silver coin (90%) was a dollar.

Disclosure: I know @rmach you young, in your lifetime the Euro will no longer exist, most companies now will not exist Gold and Silver will. Silver being the better investment, but a damn pain from the weight involved in the same currency purchase.

I could go on, but one last thing... it is completely private, no taxes, no scrutiny, when you die your heirs get it without legal hassles and or taxes.
