Well, if you say so. Nevertheless, these were never issued in gold! The shape of the top one is not even attested to from an original specimen, only from modern reproductions and the inscription on the knife is also not seen in this manner. That still makes them relatively modern, but apparently in gold! I personally have not seen any gold replicas of these pieces, but they would at least be worth melt. Maybe a bit more if you can prove that they are slightly older replicas (19-20th century).
That means nothing because the real ones were cast and often show flashings as well. But AnYangMan is right none of them were ever made in gold. Possibly someone intended them for jewelry.
Genuine examples were well-filed so that most don’t have the casting flash. Some do though when quality-control was lax, but for the bottom 2 coins, it was almost never lax.
