Some of the most valuable coins you might find are coins that are made of the wrong material. In other words, the wrong planchet was used. Below is described one example.
A 1943 Lincoln penny that soared in value because it was made from the "wrong" material reportedly has sold for $1 million.
The penny was erroneously made of bronze instead of zinc-coated steel at the San Francisco Mint, according to UPI news agency. Texas Rangers co-chairman Bob R. Simpson bought the coin from Legend Numismatics, a rare coin dealer in Lincroft, N.J...
https://abcnews.go.com/blogs/headlines/2012/09/rare-1943-penny-sells-for-1-millionThe 1943 penny is only one example of this type of error. Since most people do not have the means of analyzing metals readily available, these types of error coins can remain unrecognized for along time. One way to identify this type of error is by weight, that is why the above table can be so useful.
Unfortunately cobs that are found on the beach often are so corroded that it is difficult to tell much about them from their weight. Sometimes they've lost half or more of their weight.
Here is what VarietyErrors.com says.
Sometimes planchets for one coin denomination are fed into a coin-stamping press equipped with dies of another denomination. This results in a coin that has been stamped with a design intended for a differently sized coin. The resulting errors are prized by collectors, though they are usually caught during the manufacturing process and destroyed.
Such errors are sometimes called “double denomination” coins, but that term is also used to refer to coins struck a second time with dies of a different denomination.
Some examples include cents struck on dime planchets, nickels on cent planchets, or quarters on dime planchets. This type of error should not be confused with the much rarer mule which is a coin struck between dies that were never intended to be used together such as a coin with nickel obverse and a dime reverse.
Wrong planchet errors may also occur when the composition of the coin changes. Such situations generally arise when the mint has decided to change the alloy or plating of the coin in the new coinage year, but a few planchets from the previous year—and thus of the previous composition—have yet to be struck. Should the dies be changed for the new year while the old planchets are awaiting striking and not removed, coins using the old composition will be struck with the new year’s date...
The same VarietyErrors.com web site provides an extensive list of known coins produced on the wrong planchet along with their estimated values. Great list that includes everything from pennies to dollar coins.

Very handy list if you are a coin collector or inspect a lot of coins like any coin shooter might.

Showing Metal Rod That Was Analyzed.

What is thought to be a medieval shipwreck was found. A rod (shown above) from the wreck was found to be of an unusually high purity of iron.

I took a little walk this morning and picked up a couple cork top type bottles. I was a bit surprised to find the older bottles because I didn't see many other bottles or much glass. Usually when I find the older ones there are a lot of modern ones visible too.
I also found a painted-label Coke bottle. When I looked on the bottom, I saw it was from Hilo Hawaii. That is the first Hawaii bottle I found on the Treasure Coast. I wonder how it got to the Treasure Coast.
We're getting a good north wind this morning, and it looks like the surf will be growing.
Happy hunting,
