Collating functions are deleted when they are overridden by later calls to the collation creation functions or when the database connection is closed using sqlite3_close(). The xDestroy callback is not called if the sqlite3_create_collation_v2() function fails.
Cost of Silver Coins. For the most part, silver coins will range in price from a few dollars over spot to $10-$20 over spot per ounce. The higher the price, the more likely that there is limited quantities of the coin available due to reduced production numbers or higher demand.
This set the stage for the complete elimination of silver from our coinage by the end of 1964. Any United States dime, quarter, half dollar or dollar that is dated 1964 or earlier is made of 90% silver. In the dime series, all coins dated 1965 or later are clad coins and contain no silver at all. The value of these coins is tied directly to the price of silver. At $20 per ounce, 90% silver coins are worth about fourteen times their face value. A dime would be worth about $1.40, a quarter about $3.50, and a half dollar, about $6.00. At the same silver price of $20, 40% silver half dollars are worth approximately $2.50 each.
