sel_69l Bedrock of the Community Australia 21786 Posts	Posted 07/14/2022 08:18 am Lots of fakes of European crowns and thalers have been made. Needs investigation in this case. As an aside, same with American gold. -------------------------------------------------------------------------------------------------------------------------------------------------------------- Looks a bit coppery on the worn high points. XRF should confirm, either way. What is the color of the metal inside the drill hole? (Hint: examine in cool (blue) fluorescent light, - not warm pink light) Beware that silver can show up brown in light of low color temperature. What is the correct weight for a genuine example? Krause World coins should give that info. What is the diameter of the drill hole?, and approx. thickness of the coin at that point? Approx. weight of the metal drilled out can then be calculated, One for silver alloy at .900 fine, and one for copper alloy Density about 10 g/cc, and copper alloy 8g/cc. Weight of total coin can then be calculated, less weight of metal drilled out. for both alloys. Specific gravity testing can also be done, but that is a bit fiddly and inaccurate without appropriate equipment Report this Post to the Staff
Roma2021 Pillar of the Community Italy 1130 Posts	Posted 07/14/2022 09:18 am @sel, correct weight is 28.06, this one weighs 26.98; given the wear and hole, I don't think 1.08 is too much loss. It pings like silver, correct diamension is 40mm and this one is 40mm. It is listed at .833 silver. The drill hole through is darkened, but appears to be the same metal; no obvious evidence of plate or fused planchettes. Under loupe, the 'bronze-ish' color does not look like plating, but heavy wear. I don't have an XRF, but I would be surprised if the coin wasn't silver. It's priced at $30. Thanks for your response, certainly has me examining further. Curious to hear what others say. Report this Post to the Staff
realeswatcher Pillar of the Community United States 1962 Posts	Posted 07/14/2022 4:00 pm Looks genuine... I suspect it spent some time exposed to something that gave it that gunky toning (don't think that's copper coming through). Regardless, this is not a rare type - as a holed and horribly worn piece, it's scrap. 55 Euros bought this: https://www.ebay.com/itm/374121635547 Report this Post to the Staff
Roma2021 Pillar of the Community Italy 1130 Posts	Posted 07/14/2022 4:20 pm @reales, that was my instinct. I see no evidence under loupe of any plating; the hole is also silver toned straight through - under magnification and loupe. I'm at the point with these type things now where I consider 'what do I want more - the quickly depreciating 30 euro - or this coin?' It's a nice contrast to hold this coin in hand compared to the other example I posted a few weeks ago. I think you might be right about the other thaler being jewelry reprod., but I'll take another look in a few weeks when the price on the other thaler drops. Report this Post to the Staff

No reason to purchase a problem coin when there are so many reasonable examples out there. There isn't much detail left on this coin. But I'd buy it for melt with no hesitation.
