More silver coins on my "List"

Hey All,
Here are more silver coins on my list. I'm waiting for silver to drop a little closer to $16/oz but if I get impatient I'll get a few of these as close to $16.50 as possible.

2014 - Perth - 0.5 oz Texas/Australia Sister Cities (BU)
Mintage - 500,000 coins
$1.50/ spot
I normally don't get fractional silver but under $2/ spot from Perth might be worth looking at in person

2018 - Britannia w/ Oriental Border (BU)
Mintage 100,000 coins
$4.50/ spot
First and one time issue with oriental border of the Britannia

2018 - Royal Mint - Year of the Dog (BU)

$5.00/ spot
5th coin from the Shengxia series

2018 - Royal Mint - 10oz British Silver Queen's Beast Griffin (BU)
$3.00/ spot
Part of a 10 coin set

2015 - Native American Mint Sioux Buffalo (BU)
$2.50/ spot

I am not 100% sure on the 10oz Griffin coin so I might keep it on the list but place it at the bottom. If silver drops to close to $15 - I would have no problem getting it.

I figure for about $2/spot the Native American Buffalo is worth a peak.

If anyone already has any of these, I would love to hear your feedback .. especially if someone has the 10oz Griffin.

Cheers :):):)
