What is a scientific way of discovering the age of an object?
You may try applying The Law of Superposition, if the article in question was buried in sediment. If the item has a carbon-base (and anything that was once alive, or was MADE from something that was once alive, DOES have a carbon-based chemistry) bring it to a lab that can do Carbon-14 dating. There are also many other radioisotopes that can be used for dating, since C-14 has, geologically speaking, a rather short half-life.

Is carbon dating valid or a lie?
Carbon dating is valid for: objects that were once living (had been in equilibrium with atmospheric carbon-14 levels) objects no older than about 40,000 years (still has detectable level of carbon-14) objects that are not fossilized (carbon has not been replaced) Carbon dating often has errors (due to variations in atmospheric carbon-14 levels over time), but these can be corrected by cross-referencing with tree ring dating. Some people want carbon dating to be wrong as it may contradict their strongly held beliefs, so in their mind it must be a lie. But beliefs can be wrong (even delusional), no matter how strongly held or the source they are based on.

Why is carbon 14 dating useless for dating old coins?
Think about it for a minute. Carbon is part of ORGANIC molecules, from living things like plants and animals. When an organism dies the different isotopes of carbon gradually deteriorate; the difference in rates is what enables C-14 dating to give an approximate date range for when the organism was last alive. So the bottom line, naive answer to your question is another question - how many coins were once alive?
Asked in Biology
What are non living things made of?
most of them are actually made of metal, cloth, rubber, leather and plastic Under non-living things, there are two groups: 1) Once Alive 2) Never Alive Once alive are things that are from alive things such as the skin of the snake used to make a handbag. The snake skin is a non-living thing but it was classified under once alive. Never alive are things such as some diamonds, minerals that are extracted from the ground. They are not alive, not even from where they are extracted. That is never alive.
