Collection Shiny Round Gold Coins Stacked

Create an image featuring a collection of shiny, round gold coins stacked in a neat pile alongside a few rectangular gold bars. The coins should have generic designs, such as abstract patterns or symbols, rather than specific animals or national insignia. Remove brand names and labels, and ensure the gold bars are simply marked with a number indicating weight, without any brand identification. The background should be a smooth, dark wooden surface to enhance the luxurious appearance of the gold.
