Really like those hadleydog. They did pick up some nice coloring. I love Canadian coins, they have some of the nicest ones.

Nice looking coins, even though I'm not into toning.
I bought a roll of each denomination in 1967, and they continue to reside in my safety deposit box.
I'm sure there's not much value to them, but I really like them and plan to give them to kids and grandkids.

Hello
I'm from Barcelona Spain, and I have only two ways for information abaut Canadian coins, The Krause World Coins and this forum.
Over this quarter 1967 centennial coin, on the Krause, indicates two types:
KM#68 0.8000 Silver
KM#68a 0.5000 Silver
I have two coins, and they seem diferent. But my problem is how to clasify.
Please, do you know how to do it?
Thanks Joan

I've seen people give ways to tell the difference but I can't. The Charlton catalogue says "the two varieties are not disinguishable by appearance".
I know lots of people like it but for me toning is tarnish.

That's cool with me. In fact, if you have any tarnished coins you'd like to get rid of, send them down my way and I'll send ya back some nice shiney white ones!  |

Joan, The only way to tell is by weight. You would need a small digital scale that measures in grams. The .800 silver quarter should weigh approximately 5.83 grams. The .500 silver quarter should weigh approximately 5.05 grams. Hope this helps. |

I have to go back again to Charlton. They say the .500 and .800 are not distinguishable. The 5.07 gram coin is the nickel coin and not one of the silvers.

 with Bromac...My reading of Charlton also does not show a differentiation by weight, and no other means is mentioned. If you had a lot of samples, I'm quite sure they would "ring" differently. Of course if you have Unc coins, that would not be an adviseable test. Does anyone else have information on the "preferred or acceptable" way to differentiate these coins?  |

Sorry all. I found it through Google last night and can't remember the website. I have been looking for it again and if I find it I will post a link to it. OK, this looks like it. Now I may have misspoke and perhaps confused myself. http://www.bellaonline.com/articles/art26240.aspWhen you look at the dates it has 1967 twice and it matched up with the question asked. However, I am not a Canadian coin expert but I do have a little collection of them. Next time I will be sure to post a link to any info I find. Edited by Irishraider

You did repeat the information correctly but it is at odds with Charlton.In my opinion Charlton is the more authoritative reference.
I hate to seem like I'm dwelling on this but it's an interesting question and it actually comes up rather frequently.I have a 1967 quarter that is certified by the very respected ( in Canada for Canadian coins ) grading company ICCS and they haven't indicated .800 or .500 in their comments. I would think that if there was an easy way to tell that they would have done that.
It is possible that the only way to tell the difference would involve destroying the coin

I just found some more information on the question of telling the difference between .500 and .800 silver.
A coin dealer has responded to the question in the Candian Numismatic Association electronic bulletin. He says when buying 1967 10¢ and 25¢ dealers assume an equal mix of 50% and 80% and that the only way to tell the difference is to refine the silver. Here is someone with years of experience and a financial interest and he says there is no way to tell the difference.

So do the 1968 .500 silver quarters weigh 5.83 or 5.05? If all the silver quarters are 5.83 g, there should still be a difference in volume. I figure the .500s would contain 0.325cc Cu and .278 cc Ag, or 0.603 cc total, and the .800s would have .130cc Cu and .445cc Ag for a total of .575 (assuming 8.96g/cc for Cu and 10.49 for Ag). By that logic the .500s would have about 5% more volume than the .800s, probably difficult to measure accurately enough. The conductivity of the coins would probably be easier to measure, but silver is only about 6% more conductive than copper so the difference between the mixes would be small, and maybe surface corrosion would throw off the measurement.
