Can't help much with Top of the Vine.

Fremont .50 is common, worth $2-3 in decent shape. From Fremont Hotel on Fremont St. downtown L.V.

$5 Binions Horseshoe sounds like the 1984 issue $5. Number N1766 in the Chip Rack. Runs $15-20 in good used condition.

$1 Horseshoe is quite common. Issued 1989 but used until Becky lost the joint in early 2004. All over eBay for $4-10 depending on condition.

There is a great write up on Binion attached to a post on the board this morning. Hope this helps.
