Yes!
I used to use a stand-alone program which managed my collection. While it was much more fully featured and had a fantastic report generator, once the novelty had worn off I realised it was much more than a simple fellow like myself needed.
I discovered Numista some time later and initially I kept both catalogs updated but it became too time consuming so after a little thought I opted for Numista. It does everything I need and most of what I want. The biggest disadvantge is not being able to see the grades during a swap.
The website has already seen a lot of improvements in the time I have been here and I'm pleased to find Numista at the top of search results when researching a coin.
What chaos there would be if the website ever went offline
Non illegitimis carborundum est. Excellent advice for all coins.
Make Numismatics Great Again!
