Observations and opinions wanted on (this) Johnson Matthey gold bar

First of all, first time poster here. Thank you to the administrators for allowing me to be here.
I am looking at this 10 oz. Johnson Matthey bar, and am wondering if this is normal or within the boundaries of what is acceptable. I am seeking the opinions of those intimately familiar with cast gold bars in general, and especially those from Johnson Matthey.
The bar on several scales shows a weight just a hair under 10 ounces, 9.997 ounces as close as I can determine. In the real world, do some bars weigh just under by this small amount?
One edge on each end is finely filed, and I understand that is done on some cast bars to bring a heavy bar to weight. Are 10 ounce Johnson Matthey bars often, typically, or sometimes weight-adjusted in this way? Is this a concern?
Is this normal and considered acceptable by real world standards?
Thank you!

At 9.997 oz., you're essentially getting 10 oz of gold. Like you said, poured bars are adjusted with a file since they don't give away free gold.

Welcome to the forum.
Perth Mint guarantees their gold bars will meet minimum stated gross weight requirements. Most all other major refiners do the same. The weight you indicate is within 3/10000. There is a good probability that the bar does weigh 10 troy ounces since the major refiners have much more accurate and certified scales than most lower cost scales available to the public or even some dealers.
Many uncertified scales that can weigh 10 ounces, are not guaranteed accurate down to +/- .001 ounces needed to determine that level of accuracy. If the scales are not exactly level and fully calibrated for 10 known ounces at a given stated temperature, you may get different readings. The bar looks pretty normal to me, and the file marks do not look tampered with.
At today's gold price the amount you are stating is less than $5.75 on a +/-$20,000 bar. The gold price for only one ounce moves more than that throughout the day most the time. I think it looks pretty good and would not be concerned about the perceived weight variance.

Thank you for the replies. So, is filing pretty common on these Johnson Matthey 10 oz.t. poured bars?
What your asking is filing to get closer to the stated weight a manufacturing thing.
I've not heard of it done at a manufacturing shop.
Then again I'm not in the know.
That would be a good question for AllEngelhard.com
I would like to know also.
i like the bar to
Welcome to the forum!
From my observation, everything looks fine with that bar…

Poured cast= 10oz.
Maybe the file marks were for testing in the secondary market. I'd use a file, or a drill. That is, if an invasive test were okay by the seller.
Welcome aboard. Good way to stack.
Hello, all. A quick follow-up on this thread. First of all, thank you for the welcomes.
After purchasing a more sensitive scale and some Class 1 calibration weights, I am now pretty certain that this bar weighs the stated 10 troy oz, even taking into account stacked tolerances, and that any metal removed by the filing was most likely done at Johnson Matthey to bring it to proper weight before being put on the market.
Thank you for the education.
