Highest face value 1oz silver bullion

What’s the highest face value of silver 1oz bullion isn’t it the maples? “$5”! What’s everyone’s thoughts on stacking them just for the fact it has a high face value…..Yes i know the face value doesn’t really matter right now, but if shit hits the fan wouldn’t you think if u have to barter with people they would see the $5 mark and think it’s worth more then for example a Silver eagle which has a face value of $1!

I buy them cause i like them not because of the face value, but i was just curious on what everyone thinks…
