The two mintmarked 1919 Mercury Dimes are worth $450 in MS-63 condition. If you’re willing to step down to an MS-60 dime, you’re looking at less than half that price. With so many coins being minted, it offers a good chance to find one that adds to your collection. You can find 1919 Mercury Dimes in G-4 condition for about $3. That’s an awesome price since the silver content is currently at $1.82 (Silver spot price is hovering around $25 as I write this). So for less than $1.20 over spot, you’re getting a collectable dime with little risk.
