It's not a proof with a D mintmark right? Even if it was proof it would still show clad on the side right? Anyone have an idea what this Is?

@jrv, it might have been plated and that covered up the normally-visible copper along the edge.

Most likely it is plated, though you cannot tell if it is silver by the weight, It's specific gravity should be different though, or you could get an xrf analysis.

Agree with others that specific gravity or xrf are the only ways to know for sure. Standard clad planchet should be 11.34 grams and the 40% silver planchet would be 11.44 grams. Unfortunately, the tolerance is ± 0.454 grams (but usually much closer), so weight isn't 100% reliable. Also unfortunately, there are 302 million clad examples and (so far) 1 silver example found, so it is best to not get your hopes up. If it was me, and the weight was 11.3 grams, I might hold on to the coin but probably wouldn't spend money on getting it tested.

Weight isn't reliable as stated because the tolerance ranges for clad and 40% have a HUGE overlap. Chances are good it has been plated.
As mentioned specific gravity or an XRF gun test are going to be the only conclusive tests. SG of clad is 8.92 SG of 405 silver is 9.53 (SG tests should be done carefully because if you rush them it is easy to get and error, and they should be performed several times to make sure you are getting consistent results. that will help eliminate errors.)
An XRF test should be able to shoot through a silver plating so the key is going to be the amount of nickel it reports. It is anymore than just a mere trace you have a clad coin. A 40% silver coin could show a trace of nickel from being in contact with so many clad coins but the silver reading will be close to 80%. A plated clad coin could still show a high silver reading because most of what is read will be the plating, but if it penetrates the plating you should still get a reading of at least several % nickel. If it is not plated it should read 25% nickel.

A nice clear photo of the obverse and reverse wouldn't hurt either  |

It could be 40% silver but it's a long shot.
That first picture looks clad.
