What does 18k PG mean on gold jewelry?
18k is supposed to mean that the item is 18 karat gold. 18 karat gold is supposed to be .750 pure. 75% pure gold and 25% some other metal. Unfortunately this is not often the case. 18k may be but likely is not .750 pure. There is a legal leeway in 18k meaning, if the item is stamped 18k it may be .745 pure. Close enough to legally be stamped as 18k. But not actually. 18KP is supposed to mean 18 karat plumb. When an item is plumb, it is level or even. In this instance 18 KP would mean exactly .750 pure. Not .745 or .748 but exactly .750. 18kpg is a trick by whoever stamped it. It means that the item is 18k gold plated. Why they stamp it 18kpg is to hopefully trick the person into thinking that it is 18k plumb gold. 18kpg is not a legitimate stamp because it changes the p from plumb to gold plated. The gold industry like all things dealing with money is full of shysters and cons and it is truly a (let the buyer beware). Between grams and pennyweight and troy oz vs. avoirdupois oz. and using the decimal system vs the karat system it is further convoluted by the initials used, rgf, gf, plumb, plated and switching letters such as in 18kpg to mean 18 karat gold instead of plated gold. No one can know if something stamped 18 k plated is actually 18k or 10k or even gold to begin with because no one will test the item to determine quality of gold plating.
How much is sterling silver jewelry per gram?
1) sterling silver is 92.5% pure silver 2) Silver is about $27 per ounce 3) there are 31.1 grams in an ounce Doing the math means it is about $.80 per gram That does not mean anyone will sell an item for that as jewelry costs are in addition to the metal price. And it does not mean an individual can sell it for that much as many dealers buy USED items to melt down and refine. Thus new silver jewelry sells for $1.00-$5.00 per gram and you can sell used silver jewelry for $.50-$.70 per gram

If you have a 1990 penny shiny silver is it real?
It's probably a real penny that has been coated with something. Maybe electroplated. It might be worth something as a novelty but either way it should be worth at least 1 cent. It's either a plated novelty item with no value, or an unfinished planchet error worth a few dollars. Weigh it. If it's less than 2.5 grams, then you may have the unfinished planchet error. If it's more, then you probably have the plated novelty item.
