Hi Ian.

Small florescent dots as on both sides of the 1902 penny you bought are signs of live verd of which only a couple will be detrimental should you decide to sell.

They are probably easily removed and of no concern but better to look out for.

If a couple of dots show (live)it is always having a look at the remainder of the coin before buying.

The live verd may now only show as spots but the remainder may have left / leave corrosion.

Oxidisation and poor storage will leave a green tinge or colour.

On common coins such as the 1902 better left alone.

Its a lovely coin but take note if you start spending over £50 on another date for one.

Pete.
