I found the silver 3d below while metal detecting about 30 years ago. I am hoping that someone can tell me why the detail on the coin is concave rather than convex. It looks like it has been in a fire at some time which has damaged details on the obverse but the reverse detail is still visible. I think it's dated 1887 but could be wrong.
I don't understand why the detail on these 2 examples are convex rather than concave like the first. All 3 coins were issued in consecutive years 1887, 1888 and 1889.
I don't think that it's a legit coin. Note the straight part under the crown. That should be curved. Almost like https://en.numista.com/catalogue/exonumia201420.html
Mr Numismatist, good call. I weighed 8 coins separately and all came in around 1.3-1.4g but the suspect coin weighed 0.9g. As you say it may be counterfeit. That in itself I find interesting. Many thanks.
