Thanks Hermann for all of the tips. Are there any types of specialists that can determine whether something is laser or hand engraved? I know those people exist, just not if any actually do authenticity work.

Also, could you please point to things to look for indicative of authenticity on pictures of a piece so I can see it for myself? I would be very grateful if you could look at either at what I linked, or show me some other item. I would prefer to see something high end since those are more likely to be forgedvor reproduced.
