LCS-Local Coin Shop As for the 'gun' I gotta do some research because I am only getting "BANG BANG" gun results on the computer. Edit: found a bit of info here. http://www.scrapmetaljunkie.com/252/the-handheld-xrf-analyzer-gun-2 A bit spendy if you want to buy one, easily going up to $20k for a used one.
Cool. Maybe I should try and make one. I built an Ion Gun that shuts down the electrical system of cars. I used it once on my neighbors annoying boom box car stereo. I doesn't work anymore though. I fried it trying to increase the intensity.
And basically the gun will shoot radiation and come back telling you the exact metals and alloys with percentages and everything. It has saved that coin shop on many occasions. Their tray of fakes has grown exponentially since then and they have avoided some very tempting bad transactions with that thing. Very wise investment if you are an owner of a coin shop, especially with counterfeiting on the rise and getting better. It'll pay for itself.
Though I've not sold any 1967 Canadian personally, I've heard that many dealers just buy and sell it all as if it were 65% silver (split the difference). And to the OP, you can tell which 1968 coins are silver with a magnet. The silver ones aren't magnetic.
That is how you tell what? They're both the same. There are no distinguishing features, not even the weight is different just the content of silver. How does the catalogue tell which is different? It doesn't. That is what we've been talking about. You know, aiming a highly dangerous and extremely expensive nuclear accelerator at the coin to determine whether it is 80% or 50%.
I need to be educated on older Canadian coins. When was the last year George the 5th appeared on coinage? Aren't Canadian coins (10, 25, 50 and 1.00) prior to 1920 Sterling Silver? I just purchased three 25 cent pieces as described above, but they are so badly worn / damaged the dates can't be read. Not even worth scanning. Anyone with advice?
The switch from George V to George VI was in the mid-30s, but off hand I can't remember what date exactly. I think 1935 or 1936. EDIT: Older ones are sterling. Here's a list of the compositions: http://en.wikipedia.org/wiki/Quarter_(Canadian_coin)#History_of_Composition
[h=2]I did not know this about Canadian quarters. Interesting... Other notable dates[/h] The 1906 Small Crown is valued in the thousands of dollars even for very poor conditions. 1936 marked two valuable variations, the Bar and the Dot, both trend for over $1000 in uncirculated condition. The 1951 Low Relief was predominantly only made available in proof-like sets and have a mintage of around 500. The 1973 Large Bust is among the most desired Canadian Quarter. They sell for around $300 in Proof Like or Specimen condition, and can sell in the thousands for high end circulation strikes. The 1991 quarter had a low mintage, of 459,000 The 1992 New Brunswick quarter has several rotated die versions, with the 180 degree rotation selling for between $100 and $200 in uncirculated condition. 1999 featured mule versions of the September and November quarters. These coins do not have the 25 CENTS mark on them, making them, ironically, legal tender without face value. Either usually sells for over $10 depending on the condition of the coin. The Royal Canadian Mint estimates a combined mintage of 10,000 to 50,000 of the September and November mules. The 2000 Millennium Map Mule. Highly sought after by collectors, this is a modern rarity with about 100 known examples, as referenced in population reports of coin certification services (ICCS, CCCS, PCGS, NGC). 2000P Caribou: two examples are known to exist. They fetch $40,000 or more (ICCS has graded both in MS-64: ICCS 2010 Population report). Both are in private collections. 2000P Creativity: two are known to exist. They fetch $15,000 to $20,000 (ICCS has graded one in MS-62 and the other in MS-66: ICCS 2010 Population report). 2000P Community: five are known to exist. They fetch $12,000 to $15,000 (ICCS has graded one in MS-60, two in MS-62, and two in MS-63: ICCS 2010 Population report). [h=2][edit][/h]
Alright I finally got my hands on a magnet and turns out both of the 1968 Canadian Dimes are not silver.
So I take it that they both stuck to the magnet then. Wait, they're are made of nickel aren't they? What happened when you placed a magnet to them? In any case, I was wrong. So horribly wrong. The shame! Anyways, it seems that you have two different types of 1968 10 cents coins made of not-so-precious metal. Ok, let's have another go at it. Canadian 10 cent coin on the right: KM#72a w/Ottawa reeding on the edge and a more refine bust. Canadian 10 cent coin on the left: KM#73 w/Philadelphia reeding on the edge and a goofier bust. I believe these to be correct now. It's kinda hard when I can't view them in hand.
Thanks Lon! But their composition is still a mystery. I showed them to Firesideguy today at work, but he had no definite answers. Even if only 80% Ag I feel they were a fair buy. ($5 each).
Post a pic of the coins. Maybe somebody can help. And also, $5 isn't terrible for 80%ers. Melt right now is $4.22 per coin.
