Test Token 1.4 "d"?

i have had this test token for a number of years. It weighs 2.5g, has up-up dies and a bilingual legend. So it is very much like a TT1.4C, except it does not appear to be copper. In hand it is a very brassy yellow with some apparent greyish toning.

I had been of the view that this coin was plated in some way as the surface is not even. However, I was looking at it carefully yesterday and I now I think it is lacquered. I looks like it has some rippling plus the edge has apparent coat seams.

So today's project is to give this an acetone bath and see what happens.

I am hoping that this is perhaps an uncatalogued copper/zinc coin like TT1.6A or TT1.6B. I have never seen one of these so I am unsure what colour they would be.

I will keep you posted!

Well, that was a little disappointing. The coin was not lacquered. After the acetone bath the appearance is pretty much unchanged. I guess it just has a surface that is not as smooth as you would expect. I can only assume that this is either a copper zinc coin which has an unusual surface due to the alloy or it has been plated. I guess this needs an XRF.

In general, and not specific to your test token, RCM has used a type of lacquer that is resistant to acetone on several issues. In fact, I have often found that for these types of coins (Not all), an acetone soak makes the appearance disastrous. Example with the 5 cents from Proof sets of the early 1990s.
