MachinMachinMan Pillar of the Community Australia 1985 Posts	Posted 01/15/2026 8:41 pm Is it safe to assume this coin is .800 silver ? 2.33g https://en.numista.com/230727 Quote: Comments There is a debate about the existence of this coin struck in 50% silver and its weight. (2.33g or 2.07g) Here's what the RCM published on their web site (no mention of a 50% silver coin for 1967) : https://www.mint.ca/en/discover/can...ion/10-cents 1920 - 1967 Composition: 80% silver, 20% copper Weight (g): 2.33 Diameter (mm): 18.034 Thickness (mm): n/a Edited by MachinMachinMan 01/15/2026 8:45 pm Report this Post to the Staff

MachinMachinMan Pillar of the Community Australia 1985 Posts	Posted 01/15/2026 9:09 pm Thanks CoinForMe It's just that Numista list exact same weight, diameter and thickness for both .500 and .800 silver coins. .800: https://en.numista.com/384 .500: https://en.numista.com/230727 Report this Post to the Staff
DBM Pillar of the Community Canada 9862 Posts	Posted 01/16/2026 12:58 am They are indeed the same weight , diameter etc. Bullion dealers buy and sell them as 65% silver. Been that way for sixty years. The only reliable way to differentiate is XRF. Some people say they can ring the difference, but you can't bank on that. Literally.

MachinMachinMan Pillar of the Community Australia 1985 Posts	Posted 01/16/2026 02:03 am If silver is denser than copper how can two coins with substantially different silver content have same weight, diameter and thickness. Defies the laws of physics doesn't it? Report this Post to the Staff
DBM Pillar of the Community Canada 9862 Posts	Posted 01/16/2026 10:51 am Thickness of a coin is measured at the rim, the center part of coin can be thicker or thinner, the relief higher or lower. I'm sure a specific gravity test would reveal the difference, but it's not cost effective for bullion buyers, or grading companies. My bullion dealer has told me he can provide XRF testing at $12 per coin, if curiosity is getting the better of you I'm sure you can find someone there on the other side of the world to accommodate you.

Northerncoins Pillar of the Community Canada 2019 Posts	Posted 01/20/2026 6:46 pm Ping test may or may not work, seeing they are so close .500 or .800. I have a bunch of these that I bought years ago fresh from a roll uncirculated. They are quite nice. Looking at getting a ping tester, have seen them work, Brass coin verse Silver coin is easy to tell. These ones I doubt it. I have some older .800 can dimes to play with . Will see I guess. Not that important I suppose seeing the weight and the silver content of the tiny dimes anyways even at .800 , Unless you have a few hundred or some such. Report this Post to the Staff
1960NYGiants Pillar of the Community United States 666 Posts	Posted 01/23/2026 5:09 pm I believe the ones from the original red and black cased Specimen sets are 80% and the business strikes are 50%. Charlton also prices the proof like issue as 80%. LM of RCNA Member of CATC Report this Post to the Staff
