If you mean a silver eagle (made from the 1980s to present) you can expect to pay $1-3 above silver spot for them. At the time of writing, you can expect to pay around $31-34 or so for one. Expect to pay about double that for a proof. Keep in mind that changes in silver prices will change the price of the coin.

Pennies are currently made mostly of zinc with a thin copper coating. This change was made in the early 1980s to save money, as zinc is cheaper than copper. The copper coating gives the penny its traditional appearance.
The U.S. penny is made of copper-plated zinc rather than silver due to cost considerations. Silver is a more expensive metal than copper, making it less feasible for producing low-denomination coins like the penny.Using copper-plated zinc helps to keep production costs down while still maintaining the appearance of a copper coin.
Pennies are bronze colored because for many decades they were in fact made of copper or bronze. Those metals were chosen because they were cheap enough that they could be used in enormous amounts to make low-value coins, along with being hard enough to stand up to a lot of wear.When the price of copper went up in the 1980s the Mint had to choose a cheaper metal to avoid having pennies that were worth more than 1¢ each. Zinc was selected, partly because it's not expensive and partly because the zinc lobby has a lot of influence. Zinc is silvery in color, so to prevent confusion with dimes and to maintain the 200-year tradition of "copper" pennies, the zinc coins are plated with copper so that they look almost like their older bronze cousins.
It is incalculable.

Overall demand for electronic components grew during the 1980s, bolstered by the proliferation of personal computers and peripherals, telecommunications equipment, and the integration of electronics into industrial and consumer products.
Since 1982, U.S. pennies are made of zinc coated with a thin layer of copper. The zinc core makes up about 97.5% of the penny's weight, while the copper coating accounts for the remaining 2.5%. This composition was changed from solid copper in order to reduce production costs.
The early 1990s saw dramatic reductions in secondary silver supply. Compared with the early 1980s, silver supply from scrap during the 1990s fell to approximately half its former level

Industry growth lagged during the 1980s, due in part to foreign imports. Also, more popular solid-state components reduced demand for traditional electromechanical equipment produced by this industry.
No, it has no mintmark. Coins from the Philadelphia mint, with the exception of the War Nickels from 1942-1945 and the Susan B Anthony dollars didn't bear the "P" mintmark until the 1980s. Pennies to this day have no mintmark for the Philadelphia mint.
