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.
Silver prices per ounce remained below $10 per ounce during the 1980s, 90s and much of the early 2000s. The silver price per ounce began to climb around 2006, and over the next few years went from under $10 per ounce to around $20 per ounce in 2008. As the financial crises of 2008/2009 got underway, silver prices per ounce began to climb rapidly, eventually rising to nearly $50 per ounce in 2011.
