Molly, the receipt can look the same as the rest of your property donation receipts. You simply describe the property:
Thank you for your gift of 27 shares of IBM.
See IRS publication 1771 for receipt language donations near the back of the publication.
Please remember that per this same publication, no values are ever provided for gifts of property.
