Constitutional, or junk silver as it’s also called, is one of the best investments since it is well known, known quality of manufacture, government backed, and unlike most physical silver it is a felony to counterfeit it since it’s a legit form of US Government currency. There are many other targets for counterfeit that don’t come with felony counterfeit charges. The only downside is the price is often higher than thought and you can easily pay too much due to weird advertising (advertised at face value instead of weight) and math involved to know the exact per ounce spot price + premium is not easy or intuitive. Otherwise it’s a solid investment. Prolly the best you can get for bartering in a possible future alternate economy.
