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.
Higher Dime Values. Dime values for coins dated 1964 or earlier have the current silver price as their base value. At over $15.95 per ounce, all silver dimes are worth at least $1.20 each. However, the odds are great some of your old dimes have a higher value, hopefully much higher.
