Probably about a maximum of $20.00 and that's a RETAIL price. (the price YOU would buy it NEW for... not the price you could get for selling it for scrap or something like that).
9k gold filled material is what they used to use "back in the day" when costume jewelry started becoming very popular, the jewelry companies wanted to make a nice-looking piece of jewelry but gold was expensive as it is now, so gold plating, rolled-gold plated and gold filled jewelry started being manufactured. Unfortunately, in today's market it is of little to no value.

Markings on white gold are normally placed to indicate the level of purity of the gold. Different manufacturers use varied types of markings on their products.
4000$ easy
I'm pretty sure real gold is worth more then gold stuffed with lesser valued things.
The amount of gold you're talking about would be measured in 1000ths of a single cent in value. Gold filled is not gold, it is only plated with a few microns of it
about the same as yellow gold
If you can find somebody who will buy gold filled as scrap, a little less than sterling silver price; But most buyers wont take gold filled especially not in large quantities. Your item is not pure gold, and of very little value scrap metal wise. It could be worth a fair bit as a piece, but most gold filled rings are only of 10-25$ value at best as a sale piece itself.
When the white people found out they were worth money.
Gold filled cases are not worth much, they are plated and to difficult to separate gold from other metals. I have an 18kt solid gold accutron and the case and back stripped of all other parts is 19.2 grams
Gold Filled: Gold filled is an actual layer of gold-pressure bonded to another metal. Gold filled is not to be confused with gold plating as filled literally has 100% more gold than gold plating. Gold filled is much more valuable and tarnish resistant. It does not flake off, rub off or turn colors. As a matter of fact, anyone who can wear gold can wear gold filled without worries of any allergic reaction to the jewelry. Gold filled jewelry is an economical alternative to solid gold!
