When a coin ages it lowers the mass of a coin because usually some of the metal such as copper on a penny comes off the coin leaving it with a lighter mass then it started off with.
According to the US Mint, current one cent coins have a mass of 2.5 grams.
No, the noun 'coin' is a countnoun, the plural form is coins (one coin, six coins).
In the absence of any additional information, a coin typically has more mass than a feather. Coins are typically made of metal, which is denser and has a higher mass compared to the lightweight structure of a feather. However, it is important to note that the specific mass of each object would depend on their individual composition and size.
Drop 10 coins of the same size and mass into a container filled with water, making sure that the water that overflows from the container is collected. Now measure the volume of the water overflow an multiply it with the density of water which is 1 kg/l. Now divide the total mass by 10 to get the mass of one coin.
The difference in mass between a 1990 coin and a new one is negligible for all practical purposes, unless the currency has been redesigned. (For example, in the early 1990's the UK issued new 5p and 10p coins to replace much heavier old coins.)

Changes such as increased muscle mass and improved immune function are not commonly found in an aging body.
Aging isn't the only factor responsible for wrinkles
loss of muscle mass and strength associated with senescenceAccording to wikipedia, this is the loss of muscle tissue with aging.
The muslce will decline in size and stamina, or simply lose mass.
Pennies vary in mass over the years as a result different designs and metal ratios used to produce them. If you are referring to pennies produced in the same time period, then it may be a result of different isotopes that when accumulated result in a variation of mass.
You can obtain anti aging products on the internet, at the supermarket, drug store, mass merchandiser, or even a Dermatologist. You may also find them at specialty stores and spas.

A typical result of repairing aging skeletal muscle tissue can be improved muscle strength, function, and mobility. This repair process can help to restore muscle mass and reduce muscle weakness commonly associated with aging.

"Aging" can either be an adjective (as in, "an aging person") or a gerund (as in, "The person was aging rapidly").
