It depends on what your looking for. If it is gold then Murray and Prichard, Id are where I would go. My best finds there are 9 and 7 gram nuggets.

Because metals are usually good conductors of heat. When you touch metal at a spot that's cooler than your skin, the bit of heat that flows from your finger to the metal at that spot quickly flows onward to cooler parts of the metal ... leaving that spot still cool, and still taking heat out of your finger. If you waited around until the entire piece of metal warmed to the temperature of your skin, then the metal wouldn't feel cool any longer.
Drilling out the spot is usually fastest. Use a drill (same size as the spot) with a shallow angle grind and most times you only have to drill thru one pc. of metal. Grinding works but removes a lot of metal. Heating, the spot, is a waste of time.
Its not good to squeeze a spot period
For the most part, the reviews of the game Metal Gear Solid Portable OPS have been quite good. Game Spot has a rating of 9/10. GameRankings has a review of 87.3%.
Reputable coin dealers in your area would be best to run your old coins by 1st, as they may have a few valuables in there that could bring a good windfall. Also most of them would buy for a premium under spot as would a scrap metal dealer. If you have the time sell it on EBay on somewhere your self with spot price as your auction reserve. To find out the currents spot price for any metal at any time google is your Friend.

Wikipedia is a good spot to find where a good spot is. Ask.com is. That's all I know. I hope that helped you.
The best spot is on the seafoam islands.
