It depends on what the condition is.  Even in poor condition it's never worth less than $1 and would be worth at least the silver value.  Remember, anything is worth what a buyer is willing to pay for it.  Check recent Ebay sales, the price list on pcgs.com, or recent coin mags to get an idea.

Of the ones you listed Aluminum would be the best mostly because it is a metal.

Any legal tender coin or bill is worth its face value in commerce. There are many examples of the mony being worth more on the collector or metals markets. A 1922 penny is only worth a penny at the store, but if it has no mint mark, collectors will be falling over each other with fists full of $$ to claim it. The same is true on a smaller scale with the new quarters and nickles, as many collectors will pay a premium over face value for the right one or ones. On the metals market the valuation of the coin(s) reflects the price of its metal at the time. A silver dime is worth its weight in silver on the market, yet may be more valuable to collectors due to date and condition. It definately pays to do a bit of research if you have an old or unusual piece of currency as you just may have hit the proverbial "jackpot".

depends on the type of metal

Any metal whose concentration can be determined by ICP (inductively coupled plasma).  Pretty much any metal but mercury.

The mercury probably doesn't have much value as it is probably impure and possibly contaminated being contained in a jar for an extended period of time. The most important concern is to NOT open the jar. Mercury is very poisonous and can be deadly in large amounts such as the one that you have. You should consult with someone to ensure that it is disposed of properly, and do not attempt to dispose of the metal yourself. So in short, the mercury isn't worth much, but it's such a large amount that you want to be very careful with it. Hope this helps!

Metal prices will vary depending on how rare they are (gold, for instance, is quite rare), what the demand is for the metal is (certain metals have important uses in semiconductors and therefore are valuable), how easy it is to extract, and the level of quality or purity that is required.

Of course it's a collectible.  I got one in 1990 as a tip once and YES it is worth more.  Check it out you may have a find.

any type of heavy metal.  Like Mercury for example.

Magnesium and zinc are heavy metals , Gold is light , It does not corrode and is shiny too.It is malleable and Ductile !\nGold has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form. \nSoft, lustrous, white silver was one of the first metals known to humans. Together with gold, iridium, palladium, and platinum, it is one of the group called precious metals. Silver ornaments and decorations have been found in royal tombs dating back as far as 4000 BC.Silver is somewhat harder than gold and is second only to gold in malleability and ductility.\nSame is with silver\nRegards,\nSidra

1) you can sell your scrap metal to any scrap metal recycler. Do a local seach for scrap metal recycler or recyclers.\n\n2) when you say "metal" building that is a broad description.  I assume you mean a steel buildig possibly with galvanized or aluminum sheeting.  I assume you may even have some copper cable as well.  Each of these types of scrap metal should be separated and sent to the recycler as each type of scrap has a different value.\n\ngo to http://demolition1.blogspot.com for current U.S. Scrap Metal prices

I has about one ounce of gold. It is a common date. $20 gold pieces in general are worth a little more than the gold content. The value is dependent on the condition. If it is uncirculated--no wear--it is worth the most. With gold currently at $641, I would guess about $700. An uncirculated coin maybe $750. If it is soldered to the chain, that will lower the value to the price of gold.

In my opinion, it depends on each individuals preference for jewelry.  GOLD seems to be the favored precious metal because of its value, both by rare availability and its historical influence to our greed and vanity. PLATINUM and SILVER comes in as a close second place.\n~meow

Good question? I think it comes from platinum. A bar of pure platinum would be really expensive.
