Pan-Pac $50 gold slug weight

[Zoins]

How much do the Pan-Pac $50 round and octagonal gold slugs weigh? I checked coinfacts.com but it's silent on both.

[RWB]

2.5 times the weight of a $20

Cool. That makes sense. Thanks.

 

So the AGW of a $50 slug is 1161 grains or 2.42 troy ounces.

[123cents]

83.55 grams.

Coinfacts says the non-gold 10% is comprised of silver and copper. Is the silver part incorrect?
