how is the bird done? It looks like a bump map possibly. That part looks like a coin but the text not so much because the shadows give away that the text is sitting on the surface and not part of it. Bump maps (from limited views) or displacement mapping would look more natural (usually) since that’s more what a coin is – bumps on a surface. Without doing that (it’s more of a texture thing than a modelling thing) to do it like it currently is I would sink the text into the surface until all you can see is the rounding and caps. And of course a metallic texture, if you have reflection on it now it may not be showing because there is nothing to reflect, try using the environment channel.
