Please use caution when buying from or selling to folks you don't know or who don't have "presence" someplace such as an online shop or physical location.
You can sell your antiques and collectibles through my website for a small per item fee, for more information .... Sell Your Antiques
The Internet is full of scams. One of the biggest is that someone will offer to send you a check or money order in an amount greater than what you are asking for the item and they want you to refund the difference. DON'T DO IT. The check or money order is no good but it won't bounce until you have already sent the con man or woman money. Disclaimer
