Ok. Any idea how much I should start the bidding at and what I should have as a reserve? I'm hoping to sell them for enough to make a good contribution to a new cafe tank and seat.
Set the starting price at the absolute lowest amount
you would be willing to sell them for. If you start them lower than that, and they sell for less than you wanted, you can only blame yourself. No one here can tell you how much they are worth to you.
