1835 Quarter Anna: is it mint variation?

[Md. Shariful Islam]

Today I picked a 1835 quarter anna (as usually heavily worn) but found that it is 26mm in diameter while my all previous ones are 25mm. Does this indicate mint variation?

Per the Baldwin website 26mm or higher probably belonged to the Madras mint

It's under -  Uniform coinage\WilliamIV 1835\Quarter Anna currency

There's a lot of info - probably a little more than you want to know!
