Thinking about getting an oz of Platinum this weekend and what some opinions. I live in central USA and tend to buy online through provident metals. They currently only have 3 1 oz options for platinum a random year perth mint platypus for $89.95 over spot, a valcambi bar for $54.95 over spot, or a scotiabank bar for $49.95 over spot. My gut says since this is a flip intended purchase go with the smallest premium, but no clue if this is even a reasonable premium at ~5% premium. Any thoughts appreciated.
