Made In Florence Italy Signed Small Plate Buy My Plate - Kid Needs Help For Sale

I procured this small decorative plate (I can’t remember where… maybe a thrift). It is unique at under 5 inches across. The plate is signed on the back. It is from Florence Italy and from collection “Davidoff” which is difficult to read so it may say something else.
I want to sale this plate to help pay the medical bills and house expenses as my 13 year old daughter was diagnosed with end stage renal disease last November. She received a kidney and any monies received from the sale of this little plate will go to her medical bills.
Thank you!!!
