Need help with 1 Lb silver round??????

This evening I had a couple come in with a 1 pound silver round. Usually the 1 lb silver rounds are one troy pound and marked .999 fine at some point along the edge or on the design. This round however is not marked .999 or indicates silver anywhere. It just says ONE POUND on the design. It actually weighs 1 lb exactly , and has a 5 digit serial number.
Is any body familar with this or have an opinion. I offered to buy it only if i could verify that it is in fact .999 fine silver. What is your thoughts? I told them I would check it out this evening and let them know ??
Thanks

This is actual 1 LB (16 oz) not the troy pound 12 oz as normally seen. This along with no markings is what has me cautious?
One of the other forum members indicated just a moment ago that many are heavy silver plated with internal being lead

If you have access to a lab with the right glassware, you could do a water-displacement technique.
Another way to do that is measure thickness and width, and assuming a cylinder, calculate the volume that way.
Pure silver should be 10.5 grams per cubic centimeter.
The volume of a cylinder is "pi" X height X (diameter / 2)^2
Silver is generally heavier than most other base metals by alot (10 to 20%), so you may be able to disqualify this if it is "way too big" for the weight.
However, there are alloys that are very, very close in density.
I would imagine there is a chemistry check, but that won't help if it is a silver plate and you don't want to file into the coin.
By far the safest and easiest thing to do is simply assume that if it is not marked ".999", then it is NOT.

I agree. Caution is needed here. Do you have it in hand? if so some careful measurements could calculate the volume and compare the density to lead and silver. Or if you have a graduated cylinder it will fit into the volume can be measured pretty exactly using water displacement. --Jerry
Sorry, did that sound cynical? Maybe it IS a pound of silver. That would be cool.
I do worry about it not saying .999 or whatever on it, though. As I do about it being prooflike, with a Morgan design. I smell TV promotion.

Good find!
I really thought it was not what it appeared, I was burned once a few years ago on one, and it wont happend twice!!

Looks like the same kind of coin you have. Click the little thumbnail and it comes with a certificate showing that it's .999 fine silver. It also has a red stamped serial number of five digits. Your coin also has a five digit serial number. Who knows!!

<< <i>Many One pound coins are really one pound of copper plated with .999 fine silver.They often have a serial number on the side of the coin. They are marked ONE POUND on the reverse. These coins do weight one pound and will weight in at 454 grams. >>
So, you weighed it. You said it weight exactly one pound. Was that one pound "avoirdupois"? Or was that one troy pound?
<< <i>A true one pound .999 fine silver coin will weight 373.2 grams; as all precious metals are weighted in Troy. One troy ounce equals 31.1 grams , not the usual 28.375 grams of non-precious metals. A troy pound is only 12 troy ounces, not 16 ounce for a normal pound.
example. For a troy pound 12 X 31.1 = 373.2 grams
For a pound 16 X 28.375 = 454 grams .
Again; if the coin weights 454 grams, be suspicious as to it not being precious metal.

I had 2 of them, 1 lb as in 16 oz, no purity, no coa............APMEX paid me full silver price
