1960 Grille question

[dtkarst]

I recently picked up this chrome grille for a 60 i believe, and got it polished up like new. This made me wonder if it was a chromed grille or a polished stainless? Has very few pits and the grille support is rust free. What are these grilles worth? I got a great deal on it and the support. But it polished up really well, a lot better then any 64-66 grille ive seen. So I was wondering if anyone knew what it was. Bought it for my 61 K10 but then remembered they were different so it might be going up for sale. Thanks Ignore the spots on every picture. Awesome phone quality
