Steve Zarelli

I have been retained by the world's leading auction houses and authentication companies, as well as collectors and dealers worldwide, for my expertise in astronaut and aviation autographs. My letters have appeared in virtually every credible auction house, often accompanying some of the most rare and desirable autographed items in the hobby. 

With over 20 years as a collector and professional authenticator, I have met many astronauts, published numerous articles, contributed to books and have been on the forefront of identifying deceptive forgeries. I have a deep and comprehensive exemplar file of known authentic examples as well as documented forgery styles.

Most importantly, in my years in the hobby, I built a reputation of being a conservative analyst, passionate and ethical.
