I would like opinions from fellow hobbyists and experts. Do they look genuine or counterfeit? And what do you think the grades if they are genuine?

@cm, first welcome to CCF. Second, can you please confirm that none of these pieces are attracted to a magnet? Also, it looks like you have a digital scale. What are their weights?

With exception of 1871 which is 24.7g, the rest are 24.8g to 25.1g
Lack of details at the sword is due to wear, supposingly?
The 1871 Obverse, the "E" of NED (3 O'clock position) looks a bit different thou.
There are some dents or discontinuity on some letters like the 1873 Obverse "R" of "DER" (45 degree position). Another example, 1869 reverse the "K" of "KONINGRYK" (about 135 degree position) kind of dented by some sharp object?
None are attracted by magnets. Looking forward to your comments.

Thanks and Best Regards

@CM, ok good to know. The weights seem about right and there is some evidence of circulation wear as you point out. What about the lettering on the edge? Beyond that you could get confirmation that the coins are actually 0.945 silver as part of your investigation.

I do not have a known genuine piece as a reference for a start, so I won't know frequency a real piece resonates.

Since no telling sign that it was a fake, out of curiousity I bought one: the 1870 piece.

I touch a small spot with some Sulphur and wet it, it doesn't turns black at all after waiting 10 minutes. Then I dunk it in Sulphur 1 part: water 3 part for more than half an hour, still nothing happens. My experience with known Silver pieces is it would turn black pretty fast.

Can I conclude that it is not 94.5% Silver and it is a fake, a real good modern imitation indeed with this test?

What type of metal or metal alloy has density so identical to Silver?

Seeking enlightenment.
Best Regards

In my opinion these coins in these lower grade condition are common and aren't worth alot.

If you want to spend so much time and detail authenticating coins, might as well spend it on higher grade / value ones.

And if you really really want to authenticate them, then send it to NGC or PCGS.

Because even if we tell you its real, its just opinions from strangers. Only if it's in a NGC or PCGS case then its legit legit.

I think they are real. But I wouldn't touch them if I saw them for sale unless they were really cheap cause it's just not worth the effort collecting coins in this grade in the long term.

Thank you Numister,
Agreed your opinions.
Lastly, how cheap would you consider even buying?

Close to melt, if you paid that then it's ok I guess.

These seem more like the equivalent to the US junk silver coins that transact at silver melt or a little more.
