Question about the Breen "monographs" on gold coins

Longacre

Does anyone know whether the following "monographs" (I hope I'm using the right word) by Walter Breen on gold coins contain the same information in his enclyopedia or different information:

1. Early United States Half Eagles 1795-1838
2. Major Varieties of US Gold Dollars
3. Major Varieties of the US Three Dollar Gold Pieces
4. New Varieties of $1, $2.50, and $5.00 US Gold
5. United States Eagles
6. Varieties of United Statate Half Eagles 1839-1929
7. Varieties of US Quarter Eagles

Thanks!

I own #1, #3, #5, and #6. They have additional information not in Breen's Encyclopedia. Is it important enough to have both? I doubt it.

I have them all, and they are well worth having if you don't have to pay a fortune for them. They are now dated because Breen wrote the monographs in the 1960s. Still they of interest to those of us who like gold.
