Hello,
I realize this thread is ancient, but I'll give it a shot anyway!
commems,
A while back you posted the following:
"Here's a bit more info on the specifications for the coins.
The One Peso coins were struck in 0.800 fine silver. Each coin is 35 mm in diameter with a weight of 20.0 grams; each coin contains 0.514 ounces of silver.
The 50 Centavos coin was struck in 0.750 fine silver. It is 27 mm in diameter and weighs 10.0 grams; it contains 0.241 ounces of silver. "
I've recently been researching this 1936 set, and have found that there are reports that all 3 coins are 0.900 fine, or that they are the finenesses you report or some other variation of this.
So, I am hoping you might recall the source of your fineness information for the 1936 set.
Many thanks!
Dan

Also here: "Three Commemorative coins were minted to celebrate the Commonwealth in 1936. They show President Franklin D. Roosevelt, Commonwealth President Manuel L. Quezon and U.S. High Commissioner Frank Murphy, who also has served as the last Governor General of the Islands. The 50 Centavo commemorative has a reported mintage of 20,000 pieces, was struck in 75% silver, and weighs 10 grams (the same specifications as other 50 centavos). The two varieties of One Peso commemorative had reported mintages of 10,000 pieces. They weigh 20 grams, and are 90% silver." https://en.wikipedia.org/wiki/Coins...lippine_pesohttps://en.numista.com/catalogue/in...&wi=&sw=&p=5Apparently 1907-1947, 50 centavos were all 75% silver. Just going by what is reported online here--haven't tested! |

I appreciate the links. I've seen all of them; but they don't provide an actual hard source, such as Manila mint records (which may no longer even exist) or the like. For example, so far, in addition to what you've shared, I've seen NGC claim the 50 Centavos is 0.750 and the Pesos are both 0.900; some NGC Registry set owners show the Pesos as 0.800. Greysheet has all 3 coins at 0.900 and the MEGA Red Book has the 50 at 0.750 and Pesos at 0.800. Krause's Standard Catalog 1901-2000 has the 50 Centavos at 0.750 and the Pesos at 0.900. You get the picture. Unfortunately, all the articles on the sets by specialists that I've seen, such as the late David Lange, don't provide any fineness info. Neither does Neil Shafer's book. I don't have the Basso book, but I'm trying to track down what he says on page 48(?). If I had some lightly circulated raw examples and some precision equipment, I'd do specific gravity tests. I tried that with my sea salvaged examples, but they are so worn that any results with my rudimentary equipment are unreliable. I'm not about to crack open my nice slabbed UNCs, even in the name of furthering numismatic knowledge! Regardless, thank you for you replies. Sincerely, Dan |

Lol, I've been watching that one on ebay. Hoping to get Basso info back from a colleague who has the book, so I don't have to buy it! Thank you! |

Just popped into my head: I need access to a spectrometer! I'll try that angle.

If you do go with the spectrometer, let us know what you find out. With all the different reporting on composition of these coins, I'm pretty sure it is the only way to "closure."

I was fortunate enough to receive a reply to an enquiry on the subject that seems to put this, apparently, long running issue to rest (djm49 is me): "Hello djm49, JAA, a Collectors Society Member, used our contact form to send you the following message: I raised this question in 2013 with the late Mr. David Lange (the Director of Research at NGC). He had specimens of the 1936-M 50 Centavos and both 1936-M Pesos analyzed. The metalogical analysis confirmed that the 1936-M 50 Centavos had a fineness of .750 silver (the same fineness as the 1907 - 1921 Fifty Centavos) and both the 1936-M Roosevelt-Quezon Peso and the 1936-M Murphy-Quezon Peso had a fineness of .800 silver (the same fineness as the 1907 - 1912 Peso). See insert below for the actual text of Dave Lange's email. Date: Tue, 26 Feb 2013 16:18:47 -0500 Subject: 1936 Philippines commems From: dlange@ngccoin.comTo: We finally had examples of the 1936M 50c and peso coins to test. The results confirmed finenesses of .750 and .800, respectively. The 50c came in right on the money, while the two pesos tested were slightly finer than .800 but still indicative that this was the intended figure. David W. Lange Research Director Numismatic Guaranty Corporation (T) 941-360-3990 x152 (F) 941-360-2553 www.NGCcoin.com" BTW, the 1947 1 Peso "MacArthur" commemorative is 0.800 silver as well. That's per the US Mint, which struck it. The 50 Centavos is 0.750. https://fraser.stlouisfed.org/title...92-1965-6280Best regards, Dan |
