1946 US silver certificates are worth their face value, which is $1, $5, $10, $20, $50, or $100. However, some 1946 silver certificates may be worth more than their face value due to factors such as condition, rarity, or historical significance. For example, a 1946 $1 silver certificate in uncirculated condition may be worth several hundred dollars, while a rare 1946 $100 silver certificate could be worth tens of thousands of dollars.
