I am not 100% sure for the price at this time, i am open to offers to judge what the real value is. I am not sure how to add images here. I am looking into that.
You're a "Newbie" so this means that you are unable to post images. You are only able to post them if you either:- Reach Jr. Member - For that you need your activity to be somewhere between 30-59. You current activity stands at 6. You also need 1 merit as well to attain the rank
- Buy a Cooper Membership - You can read more about it here[1] and you can buy it here[2].
As a recommendation I highly advise you to give more information regarding the product that you are selling. cygan already gave you some nice recommendations[3] that you should definitely try to follow to increase the chance to sell it. By just using the search function of the forum you'll find dozens of examples of users selling their casascius coins[4][5][6] with far more details that the one you've made. Use them to take some information to build your own selling offer. Best of luck!
