Your friend was right about you using the wrong kind of board.

I agree with the gent that said plywood but I would go with one inch.

You don't have a picture of the table but the base/legs should be big enough to distribute the load appropriate to the flooring materials in your display room. For example, if the legs are spindly and don't distribute the weight across enough square inches and you have a vinyl floor it will be damaged.

You're generally not going to find one inch plywood at HD or pretty much anywhere else, but 3/4" is thick enough for live loads (people walking) over ~15" open spans between floor joists so it's plenty adequate for this.

Good point about the table legs, though.

I don't know what I was thinking about the 1 inch plywood. In my defense I'm used to sourcing those materials by the truck-full.

Looking at the picture and considering the actual load bearing overhang 3/4 inch should be sufficient.

If I was going to use this shelf for the stated purpose I would add feet under the two vertical boards in the center.
