Experimental Planchet? Golden 1999 NJ State Quarter with Copper Core Question.

I was wondering if anyone could help me with a coin that I have that is golden in color and has a copper core. The obvious question is whether or not this coin could be struck on an experimental planchet or not - as found with the 5 1999 state quarters (15 total as last i researched) and 1 2000 Mass. coin.
It appears to match the Type 1 description of experimental planchets but there are a few things that don't align with general 'telltale' signs that are found all over the internet which were written when the experimental planchets were first discovered.
The terms used in the telltale signs are WEIGHT, SIZE, COLOR, LOOK, EDGE, STRIKE, and REEDING and the following is what's usually found when researching this type of error..
WEIGHT - ALL examples discovered so far are OVERWEIGHT - varying from 5.9 grams to 6.3 grams.
SIZE - It will be slightly THICKER than a regular State Quarter, due to the heavier planchet.
COLOR - So far, the pieces discovered are either the same "color" as a Sacagawea Dollar, or they have a slight "green hue" to them.
LOOK - The edge is slightly rough and may have a higher rim around part of the edge.
EDGE - Some of these do NOT have a center COPPER CORE.
STRIKE - None discovered so far are proof-like in the fields.
REEDING - Some of these have incomplete reeding.
The coin I have does have the (COLOR) aspect and is definitely not proof-like in the fields (STRIKE).
I do have issues with the vague EDGE and REEDING description because anyone who took a logic course will tell you that "Some of these do NOT have a center COPPER CORE" also basically means that "Some of these MAY have a center COPPER CORE" or "Some of these have incomplete reeding" also basically means "Some of these DO NOT have incomplete reeding".
My coin does have the copper core and it does have complete reeding so in terms of the EDGE and REEDING telltale signs, I'm not sure what the correct interpretation should be on if it matches.
What's left is the WEIGHT, SIZE, and LOOK. Obviously the WEIGHT and SIZE are inter-related as a thicker size planchet would weigh more, which may also contribute to the LOOK of the coin.
The weight of the my coin is 5.72 grams and the thickness does seems to resemble that of a regular state quarter. I used a digital scale which I know may not be the most accurate but is what was available to me. I measured out a regular state quarter and got 5.64 grams but I know that there should always be some variable weight to be left accounted for. It doesn't seem to have a higher rim, but again, if it's not a thicker planchet, then it probably won't have a higher rim.
I know that the obvious answer is that it could be plated but if it is, should the edge show the copper core? The mint made gold plated coins I see have a uniform gold plating over the edge (as far as I know) so the copper isn't showing. If I'm wrong in this, please correct me.
Another obvious answer is that it is some high-school electrolysis project to coat the coin with some metal. I'm not to keen on the science behind it all but, it's hard to believe that the entire coin could go through the process but it'll leave the copper on the edge uncoated. If there's any science guys out there that could explain if it is possible, I'd appreciate the input. You can definitely see the the gold color and the coppr color on the edge.
And of course, this could simply be privately made product which I'll be the first to admit I have no clue on how to tell if it is. I'll even go as far as to say that if if is some golden mint made coin, I wouldn't know it either. Like I said, I always thought the plated coins from the mint have gold all around.
Anyway, any input would be appreciated and I thank you in advance for it. I'll try and attach some pictures so if it doesn't get though, let me know.
Try not to be to harsh on me if it turns out to be something simple that I'm totally missing. I wouldn't ask if I didn't know.
Thanks,
Jabby

an Experimental Planchet; as
others have said, it appears to
be a normal coin, either toned,
or lightly gold-plated....
Had a roll of them a few years back from a yard sale blowout of Littleton junk. I started giving them away as change. Some bozo just had to have them and whipped out a pair a twenties for the half full plastic tube I had left. I gave him the tube and took a twenty. Anything to shut him up was my main goal. No wonder Littleton made a killing.
The mint didn't make the gold plated ones, so you know, they are aftermarket. As the others have stated, this appears to probably be plated (the edge plating could have worn off or not been applied completely) or simply golden toned.
