I stopped the video halfway in to make this comment so it is possible that he mentions it. Those with limited capital to invest, may want to consider buying half dollar and silver dollar coins form the bank, if they are doing dollar for dollar exchanges. If you buy half dollars or even quarters in bulk, the chances of you getting many coins with 90% silver content are low and most banks may not actually be selling/exchanging half dollars or silver dollars right now, but it's worth a try. It can be a risk-free investment and a fun treasure hunt too!
