Identify Chips

[MCcHips]

Hello,
I recently came across some old chips:

2 - Silver Palace Downtown Las Vegas .25
2 - Las Vegas Club  .25.
2 - Horseshoe Club Las Vegas Nev .25.
2 - New Pioneer Club Downtown Las Vegas .25

Looking to get some information on them.

They were glued (you can see residue left on some of the chips) and framed how does this impact the value?  Thanks in advance for any help with this.
