Just the year does not make a coin rare.
it has no value and is by far the most rare
The 1847 Liberty Seated dollar has no known rare varieties and the coin itself is not rare or scarce.
The 1883 Morgan is a very common coin. It is not considered rare or even scarce.
It might be, I have never heard of one. One tenth of what? What year? Who and/or what is on the coin? What diameter is the coin?
The "mini coin" gives it away. It's a privately-made replica of a rare 1840 dollar, but not rare itself. It's only worth the value of whatever metal it's made from. Unless the coin's packaging states that it's made of silver, it's probably only silver-plated.
No, it is not rare. It is, however worth the silver content used to make the coin as it is 90% silver, at current silver prices it is worth just shy of $10 in silver value.
It would depend on the coin! They made many silver George V coins in 1929. It could be anywhere from a silver crown to a small penny.
Yes, unless the coin is a very rare year or mint.
It's not especially rare. In average condition, it's worth about $27.
There were 5.578 million 1933 British 50% silver Threepences minted. They are not especially valuable or rare. If you have doubts about the authenticity of your coin, take it to a reputable coin dealer for a positive identification.
