Reeding shows copper, so plating might be suspect. That said, those surfaces have been altered--not a proof.

Maybe a school science experiment on plating? Well I guess I am gonna keep it in my collection of odd finds. Thanks again!

@Captain, (I am major Capt.). Your coins do not show me re-polish coins. One coin which you say gold plating, it is the color of Ni clad took over the years.
Now go to the main.: You state that was in boxes? Which kind? Special UN sets? In follow answer (explanation) you will understand more.
The UN and special UN sets are done from Blanks which was polish by the Mint between blank cut and milling. In that year the workers was relative free so someone probably put twice the batch to be polish. Like this we can have and find only in the sets the Proof Like. This it is the history of minting process.
Your coins are Philadelphia, the strike is superb which take me to believe you have PL special UN strike and not plated or re-polish which will let marks.
Not manny like this on the market.

I disagree, this coin is post mint altered.
Plated.

@JTTC no plating will be so smooth and brilliant. Give me examples.
To be like this the coin will be plated then polish and after will be strike. What it is your theorem on this?

I agree, this is post mint.
Polished/plated.

That's a plated coin...may not have been fully submersed in the palting solution so that is why the edge isn't plated. May have juat been applied to the surfaces.

Silvio, Capt states he found them in boxes of halfs. No special coin. These have been plated somehow like KK says or polished. Maybe a product like brasso we used for brass only this time for nickel.

part of a commemorative set Sorry CU, this it is the statement of the CAPT. On other side, if it is plated, the design will have material add and will be not so clear. Dipped in some solutions? which? No solution will do this work. Was plated before strike? possible, because in that time many workers done assisted mint errors. Other thinks: if you plat something, you can not do only the surface except you has 50 million plating machine like Mint Canada has. Thanks, Edited by silviosi

This certainly could have been selectively electroplated, using a brush technique:
Brush plating (also known as selective plating) is a portable method of electroplating. Selective plating is used to apply anodized coatings and electroplated deposits in localized areas of a part without the use of an immersion tank.

Yes this could be an alternative of plating. All this Brush platins has traces on surface (characteristics for). After Brush plating an polish proceed must be involve. Other thing, Brush plating in relative thick.
