1959 Topps #505 Tony Kubek [#] (Yankees)

1952 is often thought of as Topps 1st baseball card set, but it was not.
Topps issued several smaller baseball card sets prior to their huge 1952 set.
Topps buzz word was "BIGGER is BETTER" for their 1952 Topps set which Topps described as: "GIANT IN BOTH SIZE and NUMBER of CARDS" (407).

Key card in the 1952 Topps set is #311 MICKEY MANTLE. Often called Mickey Mantle's Rookie card - BUT IT IS NOT. That honor goes to his 1951 Bowman.
1952 Topps "High Numbers" (#311-#407), are very, very scarce with an interesting story:
This HUGE set was released in series weeks apart. By the last (6th) series, baseball season was over and football starting. Candy shops had plenty of baseball cards from earlier series so most cancelled their orders for the last series creating the scarcity.

Adding interest is how Topps disposed of the now un-needed cards including THOUSANDS of 1952 Topps MICKEY MANTLE's. They dumped them into the Atlantic Ocean like most of New York's trash in those days.

This scarce 72-card test issue set was released with very limited East Coast distribution making them quite scarce. Officially simply called "Topps Baseball Photos", their serrated or "DECKLED" edge gave them the name they go by today. The 2 7/8" x 5" inch cards were sold in 2 card packs with gum or 3 card packs without for 5 cents.

Fronts are similar to b&w Exhibit Postcards from the 50's with photos and facsimile autographs. The backs make this very scarce test issue more interesting ! They feature handwritten script of player's name, team, position & date and location of the photograph as well as a mock newspaper article.

This was Topps 2nd "Deckle Edge" issue, their first being the smaller and more common 1969 Topps Deckle Edge inserts in 1969 Topps packs.

Variations of 1974 Topps Deckle Edge exist, making this issue more fun and challenging to collect. Backs can be found in gray or a much scarcer white. Also, more limited proof versions with non-scalloped edges exist and can be found with and without card numbers.
