I just found a spreadsheet I was keeping of ebay BIN prices from 2015...

Looking back on this spreadsheet has me laughing, crying, celebrating, and kicking myself. It's the buy it now price of cards I was watching in 2015. Here are some highlights I thought you might enjoy:

1909 E90-1 American Caramel Joe Jackson (PSA 1): $10,000
1909 E90-1 American Caramel Honus Wagner (PSA 3): $3,500
T206 Cy Young Portrait (PSA 1): $350
1910 E90-2 American Caramel Honus Wagner (PSA 1.5): $4,500
1914 E145 Cracker Jack Joe Jackson (PSA 1): $9,500
1933 Goudey Babe Ruth Yellow (PSA 2): $2,250
1933 Goudey Babe Ruth Batting (PSA 2): $1,800
1933 Goudey Babe Ruth Red (PSA 1): $1,500
1933 Goudey Babe Ruth Green (PSA 1): $1,000
1941 Play Ball Joe Dimaggio (PSA 3): $800
1951 Bowman Mickey Mantle (PSA 4): $6,000
1951 Bowman Willie Mays (PSA 4): $4,500
1952 Topps Willie Mays (PSA 1): $450 [I bought this!]
1952 Topps Mickey Mantle (PSA 5): $40,000
1952 Topps Jackie Robinson (PSA 2): $770 [I bought this!]
1952 Topps Roy Campanella (SGC 2.5): $500 [I bought this!]
1954 Topps Hank Aaron (SGC 20): $820 [I bought this!]

I'm glad I jumped on the 50s Topps when I did, but I certainly missed the boat on that pre war. Oh well, what's the saying - spend your time enjoying the cards you have, not crying about the ones you don't.
