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.
For silver, the spot price reflects the current price for one ounce of pure silver. Thus, a silver spot price of 17.54 means that silver is currently valued at $17.54 per ounce.What is tricky about spot price is that it is the base price of the metal; you cannot actually buy physical silver or silver ETFs at spot price.
