Angelburst I'm not saying you're wrong, but do you have any source for the changes in coin composition? My understanding is there has been no change in quarter and dime composition since silver was removed in 1965. They're now a 75/25 cupronickel coat over a 100% copper core. Pennies had some tin in them once but have gone from almost all copper to copper-coated zinc since 1982. The 75% copper 25% nickel composition of the five cent "nickel" has not changed since 1866. This is what you'll find on Wikipedia or any numismatic site, or the coinflation site I linked above. I'm not saying there couldn't be something else going on behind the scenes, but if it was documented anywhere and leaked there would be a large community that would make a big deal about it. This is all for USA coinage, of course. Most other countries are farther ahead in making their coins out of even more worthless metals, for whatever reason.
After veiwing your Post, Meta-agnostic, I went in search for the article I read in a Metal Detector Club Forum that I had happened upon but didn't think to bookmark the site. It was only "in passing" that I came across the site while looking for something else. Unfortunately, unable to locate it at this moment but I do "stand to be corrected" in this statement and I apologize for my over-sight.
"The new nickles with the wide "moon face" contain tin inlay with a nickle over coating."

From its first minting in 1866, the U.S. nickel has undergone several design changes, but the composition has largely remained the same. The nation's third president, Thomas Jefferson, has been featured in profile on the front of the five-cent piece since 1938.
The nickel comprises 75 percent copper and 25 percent nickel, making its name a bit of a misnomer. From 1942-1945, when nickel became a valuable metal during the World War II effort, the composition changed to 56 percent copper, 35 percent silver and 9 percent manganese. These coins are prized by collectors for their silver content.

The Composition of the Cent
Following is a brief chronology of the metal composition of the cent coin (penny):
•The composition was pure copper from 1793 to 1837.
•From 1837 to 1857, the cent was made of bronze (95 percent copper, and five percent tin and zinc).
•From 1857, the cent was 88 percent copper and 12 percent nickel, giving the coin a whitish appearance.
•The cent was again bronze (95 percent copper, and five percent tin and zinc) from 1864 to 1962.
(Note: In 1943, the coin's composition was changed to zinc-coated steel. This change was only for the year 1943 and was due to the critical use of copper for the war effort. However, a limited number of copper pennies were minted that year. You can read more about the rare, collectible 1943 copper penny in "What's So Special about the 1943 Copper Penny.")
•In 1962, the cent's tin content, which was quite small, was removed. That made the metal composition of the cent 95 percent copper and 5 percent zinc.
•The alloy remained 95 percent copper and 5 percent zinc until 1982, when the composition was changed to 97.5 percent zinc and 2.5 percent copper (copper-plated zinc). Cents of both compositions appeared in that year.

Bill Seeks Steel Cents, Nickels, Dimes, and Quarters
On April 25, 2013, Rep. Steve Stivers of Ohio introduced a bill in the House of Representatives which seeks to immediately alter the metallic composition of the one-cent, five cent, ten-cent, and twenty-five cent coins. The legislation would require all four coins to be minted in American steel, with the cent coated in copper to preserve the current appearance.
The cent currently has a composition of 97.5% zinc and 2.5% copper and cost the United States Mint 2.0 cents to produce and distribute during the most recent fiscal year.
The five-cent coin or "nickel" currently has a composition of 75% copper and 25% nickel and cost the US Mint 10.09 cents to produce and distribute in the latest fiscal year.
The dime and quarter both have a composition of 91.67% copper and 8.33% nickel and each cost less than their respective face values to produce.
Although the text of the bill is not yet available, a press release from Rep. Stivers notes that the majority of the copper, nickel, and zinc used to produce the cent, nickel, dime, and quarter is imported from Canada. The bill would specifically require the coins be made of American steel going forward. The appearance of the coins would not change, just the materials used to make them.
In 2011, Rep. Stivers had introduced two separate bills seeking to change the composition of the cent and nickel to steel. Subcommittee hearings were held, but neither bill was voted on.
_http://www.coinweek.com/world-mints/us-mint-news/the-coin-analyst-u-s-mint-releases-report-on-alternative-metallic-composition-for-circulating-coins/
In 2012 one dollar coins, which are now only produced for collectors, cost 21 cents each to produce, whereas last year when they were still made for circulation, they cost 18 cents. One dollar coins are made of clad manganese brass, which is what gives them their golden color, designed in part to distinguish them from quarters. Earlier modern dollars such as the Susan B. Anthony dollars were made of clad.
Coins of the same size and weight as current circulating coins but made of different metals, the study found, produce different electro-magentic signatures. That means that changes to the metallic composition and production method of our coinage would impose transition costs of the vending machine industry.
A key conclusion of the study is that changing the metallic composition of the one cent coin would not produce significant savings because the current market price of zinc is competitive with the cost of alternative metals such as steel.
In addition, the study noted that with the exception of the cent, all current circulating coins produce the electro-magnetic properties of copper. One of the main reasons further analysis is needed is that the study found that changing the electro-magnetic signature of coins other than pennies could result in significant production cost savings for the Mint, but that needs to be studied in more detail to know for sure.

All of the declassified government documents thus far have confirmed that the US government, directly or through intermediaries, has manipulated gold prices from the 1930s into the late 1990s or at least made arrangements to be able to do so. In the official records, people such as Paul Volcker, Alan Greenspan, Henry Kissinger, and others made statements confirming, at a minimum, that the US government stood ready to manipulate gold prices. Why should the US government have changed this practice in subsequent years when the existing legal authority and financial arrangements were already in place?
The value of the US dollar, despite long-term efforts by the US government and its allies to support it, has fallen about 78% against gold since December 31, 2001 (and down about 77% against silver over the same period).
In recent weeks, partly as fallout of events from the Ukraine and Crimea, there are significant efforts underway to displace the use of US dollars in major parts of international commerce. To the extent that such efforts are successful, they will weaken the dollar’s status as a global currency and lead to potentially trillions of dollars of US currency and Treasury Debt being repatriated. As this occurs, the value of the US dollar is at a high risk of falling significantly in value.
It seems to me that much of the market rigging activity by the US government and its partners and allies over the past few weeks has focused on propping up the value of a shaky US dollar. One of the major tactics pursued to support the dollar is to suppress gold and silver prices. I suspect that the recent dip in precious metals prices was pretty much all an artificial manipulation rather than a result of free market trading activities.
