Other than getting the information from the seller, this will be difficult, you can try putting Various, and if that does not work, you can try to get an estimated date from the seller's agent, this date is not being reported to the IRS.  The fair market value is what will be needed to receive the credit as per IRS Charitable Contribution Article;

If you contribute property to a qualified organization, the amount of your charitable contribution is generally the fair market value of the property at the time of the contribution. However, if the property has increased in value, you may have to make some adjustments to the amount of your deduction.
