Does my coin has bronze disease?

[MrZun]

I am goin to buy this sestertii, are these Green spots in the coin Just patina? Or should i be worried about them?

Hard to tell from the photo, it could be just patina.

Could be or could be patina. 
A soak in distilled water wouldn't hurt.
BTW - I LOVE that Victory reverse!

It does not look like bronze disease to me. Looks like a copper sulfate or carbonate patina.

The patch above the bust might be, although more likely not. If you put it in distilled water you will probably find out quickly. Keep an eye on it and keep it away from other coins.

..can't tell if its powdery from a photo, but even if it is BD it wouldn't be hard to take care of with some  Verdicare...:)

If it's bronze disease, it is likely to grow. It gets worse before it gets better.

I’m going to say that’s not BD. Looks fine to me. BD is much brighter usually.

I'd leave the coin alone and keep an eye on it. From the photo I don't see any overt signs of BD ... but an unfriendly environment could trigger it.
