Bipolar Patinas

I found this sestertius of Thrax in Baltimore yesterday, celebrating victory over those pesky Germans, VICTORIA GERMANICA. I feel sorry for collectors of moderns that will never know the joy of holding a big fat crusty sestertius.

 

Nice find JA. How was the Baltimore show? I have this one that has a bit of bipolar patina goin on. Probably should reshoot this one.

 

Great - I did some buying and selling, found a handful of cool stuff for my auctions, and had lunch and a long, interesting conversation with the guys that run Agora. Carpooled with another Coin Talk member and talked coins all the way there and back. It was a perfect day. When I die, hold the virgins - I want heaven to be one endless coin show.

 

Well maybe a couple of virgins...

 

Lol sounds like a good time.

 

I've only one ancient that does not have this. However I do have a few US coins that do.
Allow me to start making money again and a few other ancients will be coming home.

yeah, your famous "bipennis" coin

 

This Pius Sestertius would have to qualify as a multicoloured bi-polar.

 

I could only find one among my pictured ancient Chinese.




My other Bipolar

 

Interesting you raise the topic of bi-polar patinas - here is a good example:





I thought that somebody had messed with it - I like your explanation better.

 

Forgot I had this one... more of a CALICO design...


RR Anon AE Quartuncia 217-215 BC Saturn Prow BRN Craw 38/8 Sear 624

 

Here's my pic of that coin when I had it - it's downright psychedelic!

 

I just replaced my pic with yours. Mine is too blurry!

 

That coin is ex-RBW, btw, and I got it from David Hendin - nice provenance.

 

Thanks! This is one of my collection focus, and I really like this little guy. Your info Added to my data. Someday I will consolidate everything into a single data file.
