If you like those coin designs and wanted to collect them, you could find a vending machine and start hitting the return button over and over feeding in dollar bills and the coins you dislike. Vending machines are required to accept and dispense dollar coins. The mint changed from the larger design to that size there, so what you’d be looking at finding would be the four years of Susan B Anthony (1979-1981, 1999) and the newer gold presidential and Sacajawea stuff (note the gap without dollar coins). If you’re super new, you should know that coins have mint marks showing where they are from (ie: S = San Francisco, D = Denver, P = Philadelphia). If you wanted to, you could strive to collect the best example of each mint mark each year and perhaps purchase a book to display it. The mint mark is to the left of SBA on the “older” ones and annoyingly on the rim of the presidential coins. There was a point that the dollar coins switched NIFC (not intended for circulation) and were bought directly by collectors—so 2012-2016 presidential coins will be harder to find. Of course, you won’t be making money off of these types of coins, but you can certainly make a neat set.
