My kid is doing a project for art class and there will be pennies adhered to a vertical wood surface (basically completely covering the side of a decent size box). The pennies are in various conditions taken from rolls from the bank. We excluded any that were excessively worn or damaged and we didn't use too many nice shiny new ones. It is a nice warm look of varying colors/tones.

Anyhow, we need to coat them so they will maintain their current look the best we can and protect the surface a bit. Thinking of something like a clear coat of some sort. We were hoping to find something we could spray on the finished project to help it resist staining/spotting/etc. It will not be handled often and will be inside away from UV and weather so it doesn't have to be super durable or anything just a protective "coat" if you will. We wanted something that wouldn't react with the pennies or cause any unsightly discoloration. (I plan to test whatever we are going to use on a small batch of pennies before we try it on the real thing so we can make sure it looks good)

Krylon clear coat? Wax? Any ideas or help is appreciated!!

Thanks! (and please overlook and forgive me for the blasphemous use of coins :)

Krylon clear acrylic spray should work fine.

The clear Krylon acrylic spray should be fine. Like you said you were going to do, testing it on some other pennies first is a really good idea.

In the old days (even before my time) varnish used to be used.
But (not knowing any better) I'll go along with the acrylic spray suggestion.
Describe it as if there were no picture.

I sell the Krylon product at my store and always recommend it for craft projects. Never sold it for that but it should work. I assume that you don't want to do anything as involved as the 2 part epoxy pour on type product? I've seen that used in many bar tops but I'm not sure if it would be too hard to apply to your project.

@sa, just a related thought: can you rotate this object so that you are applying the protective layer with the coins horizontal? If so then you might be able to avoid drips while it dries.

Thanks for the input everyone. Sounds like Krylon fits the bill. I have some Krylon Colormax satin acrylic crystal clear spray I will use. It says indoor/outdoor non-yellowing for metal, wood, plastic, etc. I just wasn't sure about using on coins so all of your input helps. Also, Spence it does need to be applied vertically. The way it is made I unfortunately don't have the option of applying it horizontally. I will go easy as I spray it and hopefully avoid drips/runs as I go.

several thin coats are usually better than trying to do 1 thick one but be sure to check the instructions for when additional coats can be done.

I heard from a reliable source that you can use brushed one polyurethane.
