Hi Elaine,

There are probably more but the grand opening tokens I know of are:

Resort at Summerlin $5 in case
Sunset Station $5 on card
$1 Monte Carlo on card
$1 Hard Rock on card
$1 Stratosphere on card

I hope this is of some help to you. Other casinos also issued grand opening silver strikes.

Have a great weekend!!

Best regards,
