1853 1/4 G Calif Gold, Real Or Not & Grade

I am not familiar with fractional California gold.
If it were mine.
I would sent it to the best reputation TPGrader for authentication for these, and hope that I haven't wasted my fees.

Many Jewelers copies in good gold have been made of these.

Does it matter insofar as the classification of the authenticity of the coin? It is very hard to see if they are incuse or relief. I ran a porcuppine quil over them but could not make that determination.

I used a high power scope and did observe, however, that the letters do have microdots of this same feature all over the top of them; the above still applies to these.

I did recheck the weight and it is the same as the subject line states above. No matter the true method of manufacture, if the weight coincides with documented figures, wouldn't be unlikely that tungsten, for example, would be used to simulate gold on something so small?

The heavy blotchy toning suggests to me that it might not be gold. It looks like it might be one of these tokens.
