Help With My Math

You fergitched 3¢ after 1853, Half Dimes, Twenty Cent Pieces, dollars and Trade dollars.

And the red packs and white packs.

Trick question, since knives aren't silver blades.

If it's all sterling, .925*2358/20=109.0575



While you have the book open, look at the AGW. Should be 0.737



89.24-90%, depending on date



I dunno, but the date is 404. I suspect the answer they want is 0.4461 troz



22k, same as an AGE.



Gotta watch them alls tones. 243.04 dwt, 255.8 if plumb.



Prolly none, but it's supposed to have 1.18 troz.



There's no pure gold in an English sovereign, but its gold content when new was $403.70.



Reminds me of the time my wife went to Mexico and brought back some sterling bracelets for gifts. She thought markings meant something. Snookered by a five year old.

If the markings are correct, the silver value is $700.

Very nice work BF an CW an thanks for the help....

Moving on to the last 13 mind twisters.....

18. If you have a chain that is marked ".900 Plat" and weights 63.7 grams, how much pure platinum does that chain contain?

19. If you have a fork that is marked "silver inlay" and weighs 12.4 pennyweights, huch much pure silver does that fork contain?

20. If a ring is marked "14k GF" does that ring contain any gold, and if so will an employee be able to make an offer on it? (gold filled an yes, lol)

21. If you have a ring marked ".950," what type of metal is that ring likely to be?

22. If I have a silver bowl marked "coin", is that bowl likely to be silver, and if so, what level of purity? (classic lol)

23. If I have a foreign gold coin with krause book states weighs 25 grams an contains .72 pure ounces of gold, but the coin actually weighs 27 grams, should I make an offer on it? (Heck NO, lol)....

24. If the gold spot is 1529.45, what is the value of pure gold contained in one oz. gold Krugerrand?

25. If the gold spot is 1879.20, what is the value of the pure gold contained in a Mexican gold 50 peso?

26. How many pure oz. of gold does one kilogram contain?

27. If I have a group of 18K white gold that weighs 97.4 grams, how much pure gold does that group contain, and what is the full market value at a spot gold price of 1582.28 per/oz.?

28.What is the pure silver content of a pre-1965 bag of silver dimes, quarters, and half dollars that total 742.25 in spendable face value?

29.What is the common purity of early 1900's and prior foreign gold coins?

30. If I have a flatware set in which each items is marked as "silver plate", would we make an offer?

Correct answer, none. Answer they want 57.33 grams




Purt near zero.



Yes and no. But you can bet if someone wanted to give me a box of 14KGF, I'd be on it like stink on .



silver. too high to be platinum, not a common marking (22.8K) for gold.



yes, .800 fine



No gubmint puts 8% too much gold in a coin.



Poorly worded (as are most of these), but 1529.45. Now, what is the face value of that coin?



1.2056 * 1879.2 = 2265.56



If it's silver, none. If it's gold 32.15



71.02 to 73.05 grams, $3612.99 to 3716.22



OK, you got me. Most places use .715, so 530.71 oz



Oops, forgot one. 22k (.9167 fine)



Prolly not, but that's store policy, not lack of value. I know one dealer who pays 25¢ per undamaged piece, we've always paid 50¢ to $1 a pound, depending on quantity.

If your boss doesn't want it, ask if you can buy it. It's a no-lose deal.

The only difference between me and most of your test takers is only needed a calculator (and could do without it), and your folks would need reference info.

Think for a minute, what is non-magnetic silver plate?

If he was using an earth magnet what he probably felt was diamagnetism....
