That number on bottom of can is the work shift and batch number. The date is coded in the other longer number.
IIRC, Goex powder did not come around until the 1980s. Before that it was Gearhart-Owen (GOI).
So I don't think the "02 73" mark is the date of manufacture.
Regardless, unless it's a solid clump, I'd have no problems shooting it.
I am wrong and both of you are right about which set of numbers is the Goex date code.
Many thanks for the correction.
I found a post on the MLF that explains how to read the date code, and it is the longer number and not the one on top.
Here's a copy of the post that I found: SEE POST #5 --->>>

"Here's how to read the manufacture codes on the bottom of the can:
The code on the Goex can gives the granulation, the lot number, and the date of manufacture.
For instance: 02/73.00NO3B
From left to right, this breaks down as 2f granulation, lot number 73. It was manufactured in the year 2000, the month of November, on the third day of the month, and packed on the second, or "B" shift."
-----------------------------------------------------
I have a can of Goex 4F with 2 sets of numbers. one above the other.
04 83 and 10AU05B
That would mean that it's 4F, lot number 83, year 2010, August 05, packed by shift B

A coworkers dad passed away and asked if I wanted a can of black powder they found in his house. It's a red metal can of Goex ffg. with a black metal cap offset to one side. Marked " Goex Black Rifle Powder" and "American made since 1912" On the bottom is stamped in black ink, "02 73 " and a lot number. Is this to mean it was made in Feb. 1973 ? It's about 3/4 full and powder looks to be in good shape, no clumping. Still good to use ? Any input ? Thanks
kyron4, what's is the 2nd set of numbers on your can?
That 2nd set is the date code.
The numbers "02 73" stands for 2F lot 73.
The other numbers are the production date.
I apologize for the confusion.
