Is it possible to restore patina on a bronze coin? Or do I just have to be patient, expose it to air and wait a couple of decades?  It looks to me like this 1862 Straits Settlements 1 cent has been cleaned fairly aggressively... Didn't realise that when I bought it because the photo wasn't very clear (lesson learned!)  |

There are products on the market for that. Never used any so I can not recommend any brand. John1  |

There are ways to artificially accelerate the re-patination, such as heat or commercial products. However, while it will look better, it will never look the same as the original, and someone will always be able to tell.

Always a risk to attempt artificial accelerated patination, even if you know what you are doing. Most artificial patination can be identified by experienced collectors anyway.
My preference is to just let Nature do its own thing.

IMHO ,there is no way you can restore original natural patina on any coin especially Bronze or copper .  |

I've had some success using gun bluing solutions. However, you must remember there are many different brands of those and although one may work, others may ruin your coin.

Take it out of the 2x2 and set in a window sill for a couple years, flipping occasionally. It's a slow process but it helps. It can't fix a harsh cleaning but it can improve the appearance.

There is a technique called "Taco Belling". Taco Bell napkins have a high sulfur content (at least they used to) and wrapping a coin in one may yield results.
