I just bought a 1oz gold coin on eBay but it just arrived and it’s way smaller than my 1oz silver coin even though they are supposed to be the same size. Did I get scammed?

why did you even take it out of plastic sleeve? Any kind of scratch will lower the value of your coins, when you buy them don't remove them packaging.

Gold is almost twice as dense as silver. Therefore you should expect the silver coin to have a diameter about sqrt(2) = 41% larger than the gold coin. By inspection, the two sizes look about right assuming solid silver and solid gold.

They're bullion coins. Their value is their metal content and whether they'd grade MS-67 or MS-65 is irrelevant.

Check ebay completed listings. Unslabbed 1 oz gold eagles go for about $2050 and slabbed MS70 ones not even like 10% more (excluding the 'First Day of Issue' ones). Plus the grading itself costs like $50.

No, the silver coin has a bigger logo indented on it which means more of the silver is missing relative to the size of the coin, so even though the circle is bigger it's actually an optical illusion and they're the same amount of metal

The empty spaces are lower than the design elements and letters, just like damn near every coin.
