Scott numbers 1294 (sheet) and 1305C (coil) Mint copies run around $4 to purchase. The used sheet stamp is common and worth a few cents. The used coil stamp is not as common and cost a dollar or two. This is a $1 stamp, so much less common than most definitive stamps. Most used US postage stamps are worth 15 or 20 cents, the minimum amount required to catalog and stock the stamps. Unused will always be worth at least their face value. Special cancellations and different values are likely to be worth more. Consult a postage stamp catalog, usually available at your local library for exact identification and catalog values.

No US coin, including the half dollar has a crown stamp on it when it comes from the mint. Instead, if you have a US half dollar with a crown stamp in it, it was done either by a private company or individual. These stamps generally add no value to your coin and it is just worth what a damaged example of whatever year of half dollar you have is worth.
