Hi,
The first thing to do would be to start with rule number 2 from SatsLife's "How to Buy or Sell Here" thread which states....
2. Post a picture of the item you want to sell, along with your username and date/Block height next to the item. This helps to verify you actually have the item you want to sell. If you are new to the forum, post the picture at imgur.com and provide a link or use BBCode to post. Don't worry if your picture does not show up in the post. Someone with a rank higher than 'newbie' will likely add it to the thread in the following posts for you.
Good luck!

Thank you iBHK8 for your reply. Currently I'm not selling my coin. I'm just wondering should I make an auction for it or should I just peel the coin and do not take risk of selling it.
