Coins are the way to go. I own 1oz coins and 10oz and 100oz bars. I prefer the coins over the bars. Coins can be sold separately, 10oz and 100oz bars cannot be broken up. You are forced to sell the entire bar if you want to liquidate. It’s all or nothing. With coins, you can sell small, medium or large quantities if and when you want to cash out.
Just my .02.
