Hi I'm a new member at this forum. I have a question about mine victoria proof crown 1847, plain edge. Can you somehow determine the silver % without using some kind röntgen device or gravity testing. If not, does anybody knows what's the mass differences is between the two coins?
That is a beautiful coin. Someone can correct me if I'm wrong, but I am pretty sure all British silver coins, up to like 1921 or something, are .925 sterling. Here is the NGC page for this particular coin also showing that it is supposed to be .925. https://www.ngccoin.com/price-guide...wn-km-744-1847-1853-cuid-1172316-duid-1323172
Krause lists the coin as 28.2759g of 0.925 fine silver, for 0.8409 oz ASW. The silver content of this coin is completely irrelevant to the value, however - even as an impaired (cleaned) proof like you show, this is a $2k coin.
@ABcoins ! That Gothic Crown is amazing. I'm still trying to find a decent one for my British Victorian Type Set.
Super Crown!…I have a question about the date, though. mdccc is 1800, with you there, then an x means 10 to 1810. Then there is a pillar device between the x and the vii. To me this is 1817, not recognizing the pillar device for a value. Now, I have run across coins that use a highly “stylized” font in the characters, but what is that pillar/post thing? Not a normal Roman numeral I have seen. Thanks in advance...Spark edit: I figured it out. It’s a lower case L...so xl is 40...duh!…Spark
Welcome to the boards @ABcoins, and wonderful gothic crown. I've shown your pics to my wife, who said "wow ! that's a beauty ! I can gift you with one of those if you like " .... before she knew how much it would set her back Q
Those are probably your best methods of testing the alloy - 50% silver coins and 92.5% silver coins are reasonably similar in weight and any difference could easily be put down to wear/inaccuracies in production.
