Each artifact submitted is thoroughly examined for evidence of age, or signs of modern manufacturing or tampering (rechipping/restoration). We utilize state-of-the-art Stereo-magnification equipment including stereoscopic microscopes and high-definition digital computer magnification equipment. For identifying the presence of modern alterations, ultraviolet light inspection equipment is used.

We will not issue Certificates of Authenticity or rejection letters on any artifact unless we are 100% confident in our findings. On artifacts where no determination can be made, no service fees are charged.

We do not support the use of Raman Laser equipment to determine authenticity. We have simply seen far too many Laser papered reproductions to have any degree of confidence in this technique.

In addition, our Certificates of Authenticity feature many security measures to guard against reproductions.

**We are currently upgrading the COA verification system. You may receive a “not valid” response to a certificate entry during this process.  Should you require verification you can email a scan or clear picture of the front and back of the COA to:
