Gold is a pure metal with a distinct color and density, while gold plated items have a thin layer of gold over a base metal. You can tell the difference by checking for hallmarks, conducting a scratch test, or using a magnet (gold is not magnetic). Additionally, gold plated items may show signs of wear over time, revealing the base metal underneath.
LGB means the item is plated. If there is also a 925 mark it means there is silver underneath the gold plate. A magnet will tell you if the metal underneath is a ferris metal or not.
Dpl is the manufactures stamp what it stands for i couldnt tell you, but its the jewlers hallmark.
If the gold item is unhallmarked, then you can test its purity by acid testing for a definitive answer. As a preliminary, the colour of the metal can be a rough indication with the purer the gold the more yellow the metal appears.

One can tell if something is 24k gold by poking it with a sharp object. Gold is a soft metal, and the higher the karat the softer the metal, therefore if it makes a dent or leaves a mark, then the gold is 24k. Also, 24k gold is much more yellow, so, the color can help to identify 24k gold. And finally, bringing it to a jeweler to get it appraised will help to determine if it is 24k gold.
You can tell if an item is gold plated by examining for signs of wear and tear. If the base metal starts showing through, it's likely gold plated. Another way is to consult a professional jeweler who can perform a proper test to determine the gold content of the item.
One way to determine if a piece of jewelry is gold or gold-plated is to look for hallmark stamps on the jewelry indicating its purity. You can also take it to a jeweler who can perform a professional assessment using acid testing or electronic testing equipment. Gold-plated jewelry will have a thin layer of gold over a base metal, while solid gold pieces will be made entirely of gold.
Gold-tone over base metal is not the same as gold. Silver-tone over base metal is not the same thing as silver. Many base metals are used to make jewelry, and they are often coated with paint to make it look like gold or silver, but once the paint wears off, the metal can react with the skin and turn it green. This is especially true of jewelry that is made of copper and then coated with paint. Copper reacts to the sweat in a person's skin, and turns green. Gold-filled and gold-plated jewelry may also have certain base metals that react with a person's skin. The same is true of silver-plated and silver-filled. Sterling silver, Bali silver and such are not reactive and should not turn the skin green. Gold should not turn the skin green. Electroplate is another way of fusing gold or silver to base metal, and it is very durable, but if the plating ever cracks, the base metal could be reactive with the skin. The way to avoid purchasing something that will turn your skin green is to check for the tiny stamp imprinted on gold (it will tell how many carats of gold the jewelry is made of) and sterling silver (it will say sterling, and perhaps be accompanied by some numbers).
There is Assay offices who can check gold or silver purity and give report.
Well, the difference between gold and gold overlay, is that the gold 24k it is pure yellow gold metal; and yellow gold alloys it is 22k thru 10k Rhodium Plated. But is not white gold plated. Because it is yellow gold alloy's include copper, and Rhodium plated. That it is gold overlay.
Gold is non-ferrous and therefore is not attracted by a magnet. There are other metal that are attracted by a magnet but gold is not one of them. You can tell what is a ferrous metal and what is a non ferrous one but you cannot identify gold.
