Intermission: Buy and Sell

I've heard that these days people buy gold eagle coins as a form of investment. These can be used as investment products which are available in coins or ingot form. Many of those buyers buy these gold and sell them at a higher price during the time when the value of the gold.

If there are products that I wish to buy and sell, I would have to choose silver jewelries, since I know of the place where to buy them at a cheaper price. I've noticed that the price of these jewelries are also rising as the years go buy.
