how much $$$ will I net after paying all the garbage fees? Ebay + PP fees. I have never sold any item on Ebay...
All of that information is on those web sites. Grab a pencil and paper, you'll need it to do the math involved.
For a 1k coin: $100 eBay Fees or 10% $30 Paypal Fees or 3% +30c Not sure if there is a limit to how much the eBay fees can be, and I haven't sold an $1000 dollar item on eBay yet... I believe these are standard fees though. This is why we call it FeeBay. Edit: Max is $750 for eBay Fees.
Don't start your eBay career with a $1000 coin. Sell a dozen $10-50 coins first, so you get the hang of it.
Plan to lose 12% plus whatever your anticipated shipping and insurance costs are. Paypal takes their cut immediately when payment is sent. The ebay fees you pay later on an invoice they e-mail you. You can set up auto payment for ebay fees or pay them one time manually.
