1980 Rickey Henderson Rookie Card

I am now the very proud owner of the most sought after card in the 1980 Topps set. This Rickey Henderson Rookie is now mine, all mine, Hahahahaha...
Sorry there was an immense rush of blood to my head.
I have made several attempt to purchase Mr Henderson in the past few years, obviously unsuccessfully and had pretty much given up. I convinced myself that it would be the last card I would need to complete the set. However when it showed up on e-bayUK of all places, I knew it belonged to me. For most of the time I was the winning bidder and a late-ish flurry from another bidder and for a short while I thought that another Rickey had slipped through my fingers. I remained calm and determined and eventually won.
Now I move my sights onto card #580 Nolan Ryan and 30 other 1980 Topps.

Sometimes, just sometimes on E-bay

In the past I've tried to buy just about anything on e-bay, baseball related. As more items became available, I became more discerning.

Around April of this year there was a glut of cards available, possibly a 5p listing promotion. But an auction came up 'Some 70's and 80's baseball cards' and was listed without a picture. For just 99p (plus £1.00 postage) it was a slight risk. Similar I suppose to the blind trades I'm trying to arrange.

If I remember correctly the item description was as brief as the title.

I took a punt and won.

When the package finally arrived I was stunned. There was 24 cards from 1970 to 1992. Amongst the cards were:

1970 Topps #321 Lou Piniella

1972 Topps #72 Bruce Kison

1972 Topps #93 Pitching leaders

1972 Topps #95 Strikeout leaders

1972 Topps #112 Greg Luzinski

1972 Topps #103 Checklist

1972 Topps #520 Larry Bowa
1974 Topps #10 Johnny Bench

1974 Topps #136 Ricky Reuschel

1974 Topps #251 Graig Nettles

1974 Topps #280 Carl Yastrzemski

1974 Topps #315 Ron Cey

1974 Topps #562 Bucky Dent

1974 Topps #610 Dave Kingman

1980 Topps #220 Dave Concepcion

1980 Topps #544 Rick Sutcliffe

1983 Fleer #40 Paul Molitor

1983 Fleer #613 Gary Gaetti

1989 Topps #691 Roberto Kelly

1991 Fleer #524 Tommy Greene

1992 Topps #156 Manny Ramirez RC

and some cards that I have not been able to find anything about

1990 Superstars #2 Ken Griffey Jnr

1990 Superstars #3 Rickey Henderson

1990 Superstars #6 Jose Canseco

It says on the back they were 'limited' to 10,000. Is that the whole set or each card?

The highlight of the package being the 1992 Manny RC and 1974 Carl Yastremski.

However this is not just a random mixture of cards. My only possible conclusion being that the seller of these cards didn't know that some of them were collectable. Are collectable! They knew that they were significant in some way. But why list without picture or a list of the names 'Bench', 'Yastremski', or 'Molitor', 'Griffey Jnr', even 'Canseco'. Odd, very odd.
