At ebay they sell the GTX970 GPUs for about 230-250$ in Buy-Now. That should be the amount you could expect. You are a little late because lot's of people are selling the old 9xx GPUs at the moment because of the new generation. Most of the people that want to buy a GPU for around 200$ are waiting for the RX480 now

Exactly, and to make matters worse, if the 480 turns out to be exceptional value for money, nobody will be interested in the 9xx series at all, besides perhaps SLI users.
Sell it for a cheaper-than-average price now. The longer you wait, the harder and cheaper it will be to sell.
