Sitting Liberty With Liberty Capan Pole On Right Hand?

well I have about 25 coins out of 50 we found two days ago under the subfloor in a old home,while doing some plumbing work but that one and some others I couldnt identify, all silver some of them are mexican coins I think those are 8 reales coins, I will take pics , also there is some with no eagle on the revers , just some letters and numbers,

I can think of some possibilities. There are foreign coins like you describe, there are pattern US coins like you describe, there are a lot of Chinese countefeits of US patterns like you describe etc. Need to see pictures to tell you what you have,

It would be a one-in-a-million chance, but if a "brockage" error occurs during the coining process a struck coin stays on the die and is punched into the next blank planchet. This generates a negative-relief, mirror-image of the normal design on that planchet. If this were to happen for a Seated Liberty coin (obverse design) the pole would appear over the opposite arm.

I've never seen an example of a Seated Liberty brockage but they are well known for U.S. large cents.

That would be a really valuable error coin. Like everyone else said, we want pictures!
