Sure looks like copper in these pics. My concern would be that it had been plated, although the small circulation scratches may eliminate that possibility.

KM#64 reports 1 Ringgit as aluminum bronze, 24mm dia, 9.35 grams.
As such, newly minted coins should have golden color.
132,173,000 were minted for the date 1995.
If copper or bronze,
check the weight for 9.35 grams; it could be an off metal strike, the planchet intended for another coin type.
The Australian One Dollar coins are also of aluminium bronze (92% Cu, 6% Al, 2% Ni), 9.0 grams, 25mm dia, also have a golden color.

The simplest test is: what's the weight? If it weighs exactly the same as a normal 1 ringgit, then I would presume it to be altered (plated / dipped / environmental damage). If the weight is significantly different from normal, that suggests it is indeed a wrong metal planchet.
And wrong metal planchets can happen all the time; they're hardly "unique" or a "discovery of the century". They're especially common at mints which do not produce their own blanks, but rather purchase planchets from South Korea (like Australia does). I'm not sure what the situation is with the mint in Malaysia.

My first thought it was copper plated but it has few bag marks and black spots on the surface to prove that it is not copper plated maybe it was fully made of bronze without aluminium and became copper shade right on surface

The original shade of these circulation coin is in golden shade as seen by many local coin experts and dealers but they have never seen these coin in copper shade before their experience for sure these copper coin is not counterfeit as confirmed by them to be honest with you and will measure the weight of these coin first whether it is difference than the normal weight first before sending to coin grading companies for verification and hopefully receive holder as result

Looks like copper washed, not plated. Unless we know the weight, further discussion is only as good as speculation.

These circulation coin is not toning oxidation dip wash change colour plated made of copper and it is made of aluminium bronze which is normal likes other pieces for sure we are wrong of all our thought and opinion for the copper shade variation is more rare than golden shade variation because of many difference die strike during processing and both variations are considered as normal common shades likes what local coin expert dealer says explain and have to believe and agree what he said is true for his comment since he has been in these line for more than fifty years of his experience

Since you took the coin to local coin experts and dealers, did any of them run XRF? Large dealers who buy gold should have one.
This would give a definitive answer (Al yes or no).
Pretty simple.
Looking forward to seeing your old coins!

The Weight Tolerance suggests that it is struck with a planchet within tolerance of the same type aluminium bronze. I do not believe a different metal planchet was used and will stick to my belief that it was copper washed. Unless it is sent out for authentication with proper xrf - there is no real way of telling. |
