I have just started using Numista and I like it for it's convenience of a place to both identify and organize my collection. However, I find that I am missing a unique identifier for each item in my collection. For example, I have a number of US Mercury Dimes and there is no way to tell them apart in my Numista collection. Using the api to retrieve the collection there are unique record identifiers assigned by Numista to each item but there appears to be no way to view them on the website.
