I have all the accessories for my Mavic Mini and it was activated 12/25/19 I did not purchase the warranty or fly more combo and just need a price range to go off of cause im thinking about upgrading to the newest Mavic Mini. Please respond if possible. I want to trade it in for credit and recieve the newest model I am willing to pay $75

Dont quite understand your question.  If you are asking about dji "trade in value".....its gonna cost you alot more than $75 with your trade in to get the mini 2.
If you want to know what your mini is worth to sell it to someone, $300-$350.

Check eBay to get a feel for what they sell for in your area.
