Once your book is received, one of our professionals will closely examine your book and jacket. Then we will look for both obvious and subtle problems which may affect the condition and thereby the overall condition of your rare treasure. Once this examination is complete we will then assign a grade to your book. That grade ranges from a perfect MINT (10) all the way down to a zero. Then your rare book will be permanently assigned it's own unique serial number which matches it's dual holographic seals which will appear both on the Certificate issued with your book and the second, matching part of the holographic seal which will carefully be placed on the inside, back board of your book. This will forever assure that this individual book is the same book which corresponds to the certificate issued with this book with the matching number on the holographic seal. Following all these steps your book and certificate are sealed in clear, protective plastic and shipped back to you. You may decide to unseal the book and certificate or keep them permanently sealed. This is your choice. Either way, you have both the book and certificate with matching numbered holographic seals which permanently connect that certificate with your rare book.
