It depends on your preference. A silver proof set contains coins made of 90% silver, while a regular proof set does not. Silver proof sets tend to have a higher intrinsic value due to the silver content, but they may also come at a higher cost compared to regular proof sets.
No 1972 silver proof sets were made, only single Eisenhower uncirculated & proof coins were struck in 40% silver.
You can't unless you pay the $20+ to send your coin to NGC/PCGs even under magnification the ordinary person cannot tell the difference between a pf69 and pf70 coin. Of course, it is easy to tell if your coin is uncirculated or proof, a proof silver eagle will have very shiny, mirror like fields that are easy to see yourself in. An uncirculated silver eagle will be shiny, but won't be mirror like. Also, the raised part of the coin will look frosted on a proof coin but not on an uncirculated coin.
No silver coins were included in the 1973 Proof sets.
