Hi whimsical48,
We'd like to help provide the best guidance for trade-in options. In order to confirm if your iPad model is eligible for trade-in, you'll need to run through the steps online. Select the iPad you wish to purchase, and then after you select the options for your new iPad, you'll be presented to select 'Add a trade-in' option. From there, you'll be asked a few questions along with the need to enter your current iPad serial number. Once you run through that process, it will tell you if your model iPad is eligible and at what estimated quote/value. Use this link to get started: Apple Trade In - Apple
If you have any additional questions about this process, check out the 'Frequently Asked Questions' section at the bottom of the above page. Or, feel free to click on 'Have questions about buying an iPad? Chat with an iPad Specialist' at the bottom of that same page, just below the 'Add to Bag' button.
Thank you for using Apple Support Communities.
