Savings, money market, CDs, etc. are safe but offer the lowest of returns - the S&P 500 is a basket of shares in the top companies in the USA - all major mutual fund companies offer S&P 500 index funds with a tiny annual maintenance fee - pick a fund, buy shares monthly, re-invest distributions, get rich slowly - 7% return (long term) guaranteed
The last time I checked 0.7% would be closer to what banks pay these days. I remember when I opened up my first savings account as a teenager the bank paid 5%. Of course going to the bank in those days wore out my horse:-(
Unfortunately for me, I have a couple CDs that are paying 1.9% through to the end of this year. My credit union raised the rate thru the end of the month to 2.27% so I can only hope that when my two not-so-small CDs mature in 11 months, that 2.27% being offered now will be piddling.
My use of $20 was for illustrative purposes of what the Silver Eagles would be worth as a minimum, based solely on the spot price of silver and the average premium on Eagles. As for finding them at $20 now, that is no problem for current years.
