[QUOTE="Publius2, post: 24791995, member: 105571"]This is really a two-part question regarding the Capped Bust coinage; half dimes, dimes, quarters and half dollars. The first one asks how people orient their obverse and reverse photos. The second asks if there are generally accepted standards for defining die rotation. When I take photos I typically have a grid on my computer screen showing me the coin as seen through the lens of my DSLR. I align the outermost two digits on the obverse date with a horizontal grid line connecting the tops of these two digits. The reverse is aligned using the top of the denomination "5C". This is just arbitrary on my part but is based upon my assumption that the denomination is the most important of the reverse devices.

So, the question here is: What do most of you think is the "best" or preferred means of showing these coins? I am looking to see if there is any consensus of taste and also to see if there is a non-subjective reason for preferring a particular view. The second question is related to the first. In speaking to die rotation, the standard terminology refers to the reverse rotation in relation to the obverse.

I could relate here all the pros and cons of one system over another but that would unnecessarily lengthen this post. So, the question here is: What are the obverse and reverse standards used for die rotation determination of the capped best coinage, if any? I have not seen these questions addressed in the literature. It may be old hat to you more-experienced numismatists but new material to me. [ATTACH=full]1586093[/ATTACH][/QUOTE]
