You are looking at a perfect example of the 2016 100th anniversary gold commemorative coin.  First day of issue and the most sought after autographed signature on the market.

"MARCANTI"

I've been watching for the past few months and I've never seen a Marcanti autographed "PCGS"  SP-70

100th anniversary

First day of issue

I've checked on and off over the past few months.  Through E-bay, Heritage Auctions and Great Collection's websites. I have not been able to find any information on recent or past sales. Of this Coin even listed honestly. 

I've decided to add a portion of my sale to charity. Because I was diagnosed with Multiple Myeloma a little over a year and a half ago.  I take weekly kemo treatments that, from my understanding.  I have to do for the rest of my life.  Because there is no apparent cure for this type of cancer. Along with many others.  I hope you can see the importance of everyone's help in finding cures for our most debilitating diseases.  As I never really thought of things like that,  until it happened to me. 

I went from working in construction and remodeling,  which I loved doing.  To 3 weeks in the hospital.  Major back surgery.  Right hip replacement a week after that.  Due to tumors.

3 months of radiation therapy, learning to walk again without a walker.  Waring a bulky back brace constantly and of course the lifetime of weekly kemo treatments.

So please find it in your heart to donate to a charity that you have a connection with. It's deducted from your ebay fees,  so give it to something that matters and not a bunch of corporate big wigs.

I truly miss not being able to do the work that I've done for so long.  And after a year and a half.  I still have issues walking and I stay very sick at my stomach all the time. 

PCGS has the Coin listed but no listing for any autograph dimes.  That I have found.

So good luck and I wish you best in your search and journey.
