You can sell them anywhere you wish.But there are several people on the forum that will buy them also.Lazersteve bought many pounds from me in the past.
"Vintage 1/10 12K gold filled eyeglass frames
5 lbs " am I wrong in assuming that would yield 1/4 lb of gold?

No it would yield 1/3 of a pound if they were all clean and free of any contaminants,and were not worn down in any way.
I calculate 1/4 pound also. (1/10) x (12/24) x 5 = .1 x .5 x 5 = .25#. Of course, that assumes no glass, no plastic, no screws, no wear.

5(lb)x16(oz)x28(gr)=2240(oz)
2240(oz)x 1/10x .5(12/24k/ 28(gr av)= 4 oz. av
2240(oz)x 1/10x .5(12/24k)/31.1(grT)=3.6oz.troy
5(lb)x16(oz)x28(gr)=2240(oz)
2240(oz)x 1/10x .5(12/24k/ 28(gr av)= 4 oz. av
2240(oz)x 1/10x .5(12/24k)/31.1(grT)=3.6oz.troy
Avoirdupois (av) pounds and troy pounds = Apples and oranges. You can't mix them, mathematically, unless you do it right. Actually, 5 av pounds = (14.58/12) x 5 = 6.075 troy pounds
I assume he's talking av (standard US) pounds, since hardly anyone uses troy pounds, at least in the gold business in the US. In 45 years in this business, I don't remember using troy pounds once.
There are 454 grams and 14.58 tr.oz. in an av pound.
1/10, 12K gold filled is .1 x .5 = .05 (5%) gold.
There are 31.1 grams in a troy oz
5 pounds (av) = 5 x 454 = 2270 grams
Total gold = 2270 x .05 = 113.5 grams
This is 113.5/31.1 = 3.65 tr.oz.
Total gold in av pounds = 3.65/14.58 = 0.25 av pounds = 1/4 av pound.
The simplest way is (5 av pounds) x .05 = .25 av pounds
If you had 5 troy pounds, the total gold would be 5 x .05 = .25 troy pounds = 1/4 troy pound
Gotta pick one or the other. Can't change horses in mid-stream. Also, you made an error at the end and need to invert the division. 3.6 ozT = 3.6/12 = 0.30 lbT. And, 3.33 lbT isn't 1/3 lbT, it is 3-1/3 lbT.

Sorry about that.I have never heard of gold weighed in av.
When I sell my material it is always weighed in av pounds,yet when I have gold it is weighed in troy.
But I understand where you got your result from now.I editted my earlier post

The units used are usually a matter of convention, which can vary from country to country, industry to industry, and deal to deal. I just have never seen pure gold bought or sold by the pound, whether av or troy - if it does happen, it's very uncommon, at least in the US. It's always been in troy oz, grams, or dwt, but usually it's weighed in grams and then converted to troy oz. Anything works as long as you keep the numbers straight, define your terms, and everyone knows and understands what is going on.
For impure materials, there is more latitude. I have bought both karat gold (just a few times) and gold filled (often) by the av pound, but never by the troy pound. Plated and electronics materials are most always bought and sold by the av pound in the US. In most other countries, they are usually sold by the kilogram (about 2.2 pounds).
Sometimes, I feel that some people use less common units, such as pennyweights (dwt), just to confuse the issue. Dwts are about 1.55 times larger than a gram and, therefore, a dwt of gold is worth 1.55 times more than a gram of gold. If Joe Blow sees a place that's paying $15/gram for 10K, at a $1350 mkt, and another place that's paying $20/dwt, he might sell to the latter because, not knowing the difference in a dwt and a gram, it sounds like more. However, at $20/dwt, he's only getting $12.90/g.
In the jewelry industry and, I think, in the dental industry, the troy system is used more often. For example, troy grains (1/480 tr.oz.) are used. Here again, though, I had rarely seen grains used until I came to this forum, mainly from Harold. They are not used in the primary gold industry, itself, at least not to my experience.

I also get a quarter pound
(454 x 5 x .5 x .1) =113.5

Nope. The horse wouldnt feel it.
After snapping off the nose pads and accounting for screw weight, there are 3,081 grams of clean, never used, eyeglass bridges, frames, and temple pieces, all marked 1/10 12k GF. I looked at every bridge piece and verified the stamping on all pieces.
I called Ohio Precious Metals refinery in Jackson, OH, and was referred to a man named Walter. I talked with Walter and he said that he had owned Ohio Precious Metals, sold the company, retired, and now has a company "My Gold Trade" and is interested in buying the gold. He seemed very knowledgable and honest. Does anyone have experience with these companies?

Most would back me up when I say,you'd probably have a better and more fair experience selling to someone on the forum.I cannot afford them right now,or else I would just buy them.There are many others here that I am sure would like the opportunity,and I am telling them to speak up now.
You have a total of around $6700 in gold there.Do not expect to get that though,there is a lot of chemicals,time,and labor involved.I am sure whomever you decide to sell to will treat you fairly.If you want any of us to vouch for the potential buyer just ask,or send a PM to one of the moderators,they know just about everyone on here,on a personal level.I hope this helps you and I hope you get a fair deal.

I've had a few offers, and all except one were for a percentage of the refined gold.
One offer was to buy the material, before refining.
Since the money is needed before Christmas, I think I will have to sell as pre-refined gold.
The pre-refined offer is this: he will buy the 1/10 12k GF by setting the gold content at 3.75% of the total weight (total weight is 2987 grams with nosepads and screws removed from the bridges). Then, based on the spot price of gold, he will pay 80% of that amount. I realize 3.75% is less than the 5% that should be in the material, but from his experience he said that it will be less than that. Although all of the material is clearly stamped, there is some risk that the gold content could be less than 5%?
Does this seem like a fair deal?

The dental industry uses dwt's commonly, or at least they did when I was actively refining. One of my customers, a dentist, sent me a large batch of filings (thought to be sulfated silver, but were filings from dental gold alloy---the property of a deceased friend, also a dentist).goldsilverpro said:
Amongst the materials I received were some tiny "ingots" of dental alloy, tidy little squares, each 1 dwt., and marked accordingly.
I don't recall, ever, seeing anything marked in troy pounds.
