The shroud has been dated to the first century AD by several methods.
"Moreover, other dating methods agree in the assignment of the TS to the first century AD [5,10,11,12]. Spectroscopic methods, based on Fourier Transform Infrared spectroscopy/Attenuated Total Reflectance [10] and Raman spectroscopy [11], date the Shroud to 300 Before Christ (BC) ± 400 years and 200 BC ± 500 years, respectively. The mechanical multi-parametric method, based on an analysis of five parameters, including the breaking load and Young’s modulus and the loss factor, after an adequate calibration based on the results of two dozen samples of known age, dates TS as 400 AD ± 400 years old [12]. Estimates of the kinetic constants for the loss of vanillin from lignin suggest that TS has an age range from 1300 to 3000 years [5]. A recent numismatic analysis [13] proposes that TS was already present in 692 AD."

Hilarious!
If this paper is to be believed, the Shroud could date to anything from 300 to 1000 years before Jesus was even born.
I'm not sure this is the definitive proof you were hoping it would be.
ETA: "Numismatic"? Are there images of coins on the Shroud?
