I dont have heaps of gold but... Fractionals are a good way to go IMO. I'm a big fan of the Valcambi 50gm Combibars, which are 50 1gm bars kinda fussed together that you can separate and sell one at a time, and you can buy them at the 50gm premium and sell them with the 1gm premium, which is a lot higher because of size. Also a big fan of the fractional Perth Mint Kangaroos, 1/10oz and 1/4oz are both good sizes. I own a 1/10oz kanga and a 1/25oz Proof, one more for Bullion and the other for more Numismatic/collecter value.
A lot more now than back in 2020. Why? Have a gander at what is top of the Billboard Charts and what's #1 Trend in Music category on YouTube.
Interesting you should say that serial. Who would you sell them to and for spot plus what? Dealers in Sydney such as KJC and Jaggards sell them with big margins and only buy well below spot. I have some bullion sov's as well as those proof double's I mentioned the other day.
