Tcma postcards, questions

[billyb]

Hi All,
I have seldom posted here in the post War area, but I had someone approach me with 24 of these TCMA, ALL-TIME GREATS postcards. The years appears to be 73 - 75, but some have both, 1973 on front and 1975 on the back. And some do not have anything stamped on back.
They are somewhat difficult to search online, as I have not found a 1973 or 75 checklist, or value list. Ebay sellers do not give them much value, $1 to $10, according to condition and subject.
So am I correct to assume, the ones with no back, and 1973 are indeed 1973 postcards? And the ones with 1973 on front and 1975 on back are 1975 postcards?
But what year are they with no years stamped either side. I have a Cy Young (shown), with no year on front and plain back. I then have three with no year on front (see Keeler photo), and are stamped on back, but no year stamped in front of the "TCMA" where others show the year "1975". (see Keeler and Speaker backs).
It appears that all or most of these cards were printed in 1973, but only so many were issued in 1973 and the rest in 1975. And in the case of the ones with no year, they just escaped the printing process and were a mistake
Am I correct in my assumption or does anyone else have further information.
Thank you.
