Welcome, @Collecting Nut ! I'm glad to see you've caught the ancient coin bug! I hope you'll not only show us more of your collection in the future, but that you join us in discussing and appreciating others' coins, too. One thing that would help everyone appreciate your coin would be to crop the photo. Nobody wants to see 90% envelope and 10% coin. People want to see 90% coin, like this: And with a little bit of photo processing, you can combine the images and adjust the color of the background:
Also, if you told everyone the diameter in mm and the weight of the coin in grams, it would help us to appreciate that this was not a denarius, but an as -- made of bronze and measuring about 26 mm in diameter -- like this one from the British Museum:
Isn't it amazing how a better photo enabled us to realize the SC in the reverse field meant this was not a denarius? Thank you for the effort. It is easier to help those who make it easier to help them. While the coin is not high grade, an as that looks like this is a much better item than a denarius that has those same faults.
