In the late 60's a company out of San Clemente CA known as the '99 Company' was offering 'First Day' coin issuance using a postal authority postmark as proof of day of issuance. The Company produced a special window envelope which displayed the coin, ( obverse & reverse) and a side overlap flap that was sealed with a postage stamp overlapping to seal and then postmarked on the day of coin issuance. This was a forerunner to the certification of now offered by numanistic services. My question relates to FDC covers which reflect both a stamp First Day Cover with a corresponding day of issues for new coinage. (I suspect that I may have to register in the 'Coin Forum' to seek additional information,) but I am curious if there are any 'cover collectors' that might have some knowledge of this short lived 'collectible' item.



The first scan postmark is for the day of issuance of the coin.
The second scan shows a First Day of Issue postmark for the stamp and the coin
