Hello From Poland !

Where was it moved?

It was in the Welcome forum. I moved it here, to the US Classic forum.

As mentioned, please post individual photos of each coin, front and back. Try to take them straight-on, not at an angle and make sure the whole surface is lighted and the camera is focused. The better the pictures, the better the information you will get!

I don't see anything about your 1904-S Liberty double eagle that looks counterfeit, but that's no guarantee it's the real thing. Many forgeries exist. First thing is to check the weight on an accurate scale. It should weigh very close to 33.4 grams. You should also check with a magnet to make sure it is not a gold-plated steel replica.

Your coin appears to have little or no wear and is lustrous. It could grade anywhere from AU-55 to maybe MS-64 based on these images. This date is common in circulated grades and the value is related to the gold content. $1300-1400 might be an accurate guess on value in AU. An MS-64 certified by a grading service like PCGS or NGC will typically sell for around $2,000 at auction.

We will look forward to seeing the rest of your collection.

One other thing that has not been mentioned. Do not try to clean or polish the coins at all. That is an almost guaranteed way to remove numismatic value of the coin. Unfortunately, the second photo above has a lot of faint lines that look like evidence of cleaning or wiping.

Nice coin though

Do you have pictures o the others?

Do not clean coins. Handle collectibles with cotton gloves.

Hello. Your coins are interesting, if only they could talk.

Hate to be the bearer of bad news but those gold coins look suspect in my opinion, likely counterfeits.

The coins all look pretty good to me in terms of authenticity. If your scale is accurate the 33.4 grams on the 1904-S is right where the weight should be. Many double eagles found their way to Europe in the early 1900's so it's not completely unlikely someone put these away many years ago.

The coins are all in the AU to MS-60 range, with varying levels of abrasion, hairline scratches, and slight wear. All are common dates with no premium value except in high grade and I think none of these would qualify. So, value should be closely linked to the spot price of gold, plus a small numismatic premium. Bullion value for double eagles is currently around $1100 USD. My local coin shop would tack on an extra $200 or so and retail similar pieces for around $1300; I would think a reputable dealer would offer maybe $1200 each for yours if satisfied they were genuine.

If you really want confirm authenticity the best way is to send them to be graded. However, if you want to sell and are able to get offers in that range I see no reason to spend money on grading fees.

It's exciting that you found such a potentially valuable stash; congratulations! Please let us know what happens next with your treasures!
