Hello all. Just joined because I have a question regarding the silver maple leafs. I have purchased 3 of these coins recently, 2011 mint year and am wondering the specs for this coin? I can't seem to find the thickness of these. I have seen it being listed as 2.84 mm, 3.15 mm, and 3.29 mm. Mine are coming in averaging around the 3.15mm mark. The weights are between 31.3g and 31.5g. Diameter between 38.15 and 38.16. So I am just worried that they seem off. I am pretty new to this.

Where did you buy the maple leafs? And you shouldn't worry I'm pretty sure they're authentic.

Hi, I bought them from a company called peracto corp. The first one I bought from them was on ebay, and the other 2 from their online site. I was just worried because I cannot find a for sure thickness posted anywhere. Can anyone please confirm the actual thickness these are supposed to be? Thanks for the replies. Edited by Jump_Steady

I forgot to ask what is the correct way to measure thickness on coins? I have a digital vernier caliper.Do you measure on the very edge or across the coin? And for weights, I use a digital scale and another thing I use is rare earth magnets to check for magnetics.

I've never measured one. A general purpose digital scale has a margin of error well within what you have described as the weight. Given a sample of two with one known good it's pretty hard to fake that. What I suggest you do is post the question to the RCM's facebook page (they are slow give them time) or write them directly. |

I noticed that problem too. right now SML are shipped in tubes, you can fit in 26 SML coins in a tube, but if you put year 1999 SML into the tube, it can only hold 24 coins.

bullion coins can be a bit off. Your specs sounds about right, though I would check that your scale is set up right (measure the same coin 3-4 times, pressing down on the scale in between measures to see if you get the same figure). Could be that your scale does not measure in fine enough increments.

I wouldn't worry about thickness if diameter, weight and magnetism are OK.

All my maples vary too. I only got 1 piece that was 31.1 grams. All the rest are over weight. Even with didgital callipers, the thickness varies. I often woundered if a thick coin was a light strike or thin coin a heavey strike. They do not look any different under magnification.

gold maple leaf has same issue, one can get in and out of a 30mm capsule easily, one got jammed.
here is my question, is it even possible to keep the precision down to 0.01g and 0.01 mm when making a coin?
here is a sample
1/25 Ounce Pure Gold Coin - Boreal Forest (2011)
Mintage Limited to 2500 coins worldwide
Composition99.99% pure gold
Finishproof
Weight (g) 1.27
Diameter (mm) 13.92
Edge serrated

Yes, but at a far higher cost than it's worth. You'll often find those numbers listed with a tolerance, just like car engine parts.

thank you all for the replies, it has helped to ease my mind. Being new to this, I am not keen on how coins are struck etc, and how there can be differences depending on different variables. I thought since the coin is listed as being 38 mm in diameter and such, that it had to be spot on 38 mm, or a certain mm in thickness, but since the weight checks out and the diameter is slightly over 38 mm, I now know that chances are that it is the real deal.
