Personal notes in Washington 1/4 dollar of the USA

The personal notes are left by mistake in the mintage section of the article
https://en.numista.com/catalogue/pieces54.html

They mention different types of the Reverse. There are no hits how to distinguish them. Can the lines of different years be merged, for the description is useless now? Or may be an author will reveal his/her top secrets about his/her personal notes: maybe they are not A, B C but 1, 2 and 5 in numismatics?

It does describe the difference, just not very clearly. There are regular circulation strikes, then there is a regular proof strike, and then there is what essentially amounts to an error version where the obverse is a circulation strike, but the reverse is a proof strike. The phrasing could probably be made clearer.

Exactly.
A collector has coin in hands. This coin is of business strike. The text gives idea: there are two types.
There is no criterium, how to distinguish them in the article.

It means that the remark is just a personal note of someone, who misuses Numista catalog.
That is why to merge the lines and remove remark is a must.

Sent a note to the referee.

I started some time ago….. OK, let's go.

Yes, let's.

 

The Type B reverses need to stay put on the coin page.  They are not error coins.  From 1956 to 1964 the US Mint used proof die reverses to make business strike coins.  They did not make the same mistake 9 years in a row.  It was done on purpose.  There are differences between them.  One is the space between the E and the S in STATES.  On the left is the normal business strike.  On the right is a proof reverse.
