All of those appear to be by Williams Gaming (WMS). If you visit their website, they have a great search capability that allows you to enter the game name and it shows you a picture. (Except Crocodile Cash, as it is an older game, perhaps not still supported.)

But the others are. Here is the link to Village People: http://www.wms.com/Games/Video/InnovationSeries/MoneyBurst/Pages/VillagePeople.aspx

If you notice, it looks like WMS machines only have a top glass (no belly glass) and in some instances, they have an add-on 'can' (to the top of the machine) for back-lite panels, like your Jackpot Party. Most odd shaped panels, like that, are made of clear plastic with a colored, opaque sticker or applique. (Does that describe the Party Jackpot thing?)

It is farly simple to display glass (and the plastic) with the use of mirror hangers or clips. Available at any hardware store and many drug stores, Wal-Marts, etc.

As for value... Generally speaking, slot glass has a greater value when a casino name or logo is present. The next level of value is when the subject matter or theme is of greater popularity (Munsters, Star Wars, etc.). The items you are showing are nice, but not of higher value. If available at $10 each, it would be a fair value, with a discount to buy them all together.

But this is just my opinion!

If you think they look cool, which they do, and they are available at a price within your budget, then buy them. But they need to be next to free in order to buy them for re-sale in mind, as shipping is a killer! Notice that Leo T., is selling his glass with local pick-up as a requirement.

I hope this helps!
