Official classic car miniature collection solid sterling silver?

The collection consists of 63 mini ingots, less than an inch long and perhaps a half inch wide, very thin made of .925 sterling silver. Each weighs about a tenth of an ounce. So 6.3 "regular" ounces is close to the total weight of the collection (178grams roughly). With the current price (Dec 2012)of silver around 32-34$ per TROY ounce for .999 pure silver, this collection is worth somewhere around 160-180$ depending on the daily silver fluctuations. The Troy ounce is used for precious metals and is roughly 3 grams more than an ounce, about 31g Troy and 28g Oz.
