Could You Help US With Double Eagles, Please?

1858 - very scarce in AU/MS condition. it could be worth anywhere from $1000 to $10000.
1867S - none known in MS63+, AU or better are extreme rarities.
1877 - common date but scarce in uncirculated condition. dont expect much more than gold value unless it is uncirculated.
1878 - common date - gold value unless uncirculated
1879 - most uncirculated pieces will have very reflective surfaces. those are worth $1000+ but circulated ones are common.
1882 - there are more counterfeits than genuine of this date. there are about 25 known. removed mint mark is a common counterfeit, as well as casts and transfer dies. this one needs to be authenticated. if its a removed mint mark, the bottom of the second 8 in the date will be above the bottom of the first 8. genuine philadelphia coins of this year were the opposite.
1883 - only proofs were minted and theres only about 20 known. needs authentication
1883S - common unless uncirculated.
1884 and 1884S - 1884 is proof only with only about 20 known to exist. 1884S is very common.
1888S - very common date
1893 - common date
1894 - very common
1895S - common date
1897 - very common date, in fact, I have this date =)
1900 - very common
1903S - very common
1904 - easiest one to get. even uncirculated coins arent worth much more than the gold
1906S - very common
1908 - this date has two major die varieties. neither is worth much more than the gold. one variety has IN GOD WE TRUST above the sun on the reverse and the other does not.
1924 - most common of the type
1925D - a lot were minted, but most were melted. an altered mint mark is a common counterfeit for this date. needs authentication. a genuine 25d is worth a few thousand.
1927 - 2nd most common of the type.

**the coins I described as common are worth about 700-900 depending on condition, but uncirculated common dates will be from $750-1500.

I would get these coins authenticated before I brought them back to the sates. What if you pay all the fees for a bunch of common dates, and a handfull of fakes? (yeah, lord forbid!) But I think selling this collection, a collection someone obviously took great pride in, would be a foolish thing to do in the near future. Take some time to enjoy what most people will never possess.
