Thanks but not worth messing with one card trades... Easier to buy on Ebay. I bought ten green refractors #d to 399 for $10 last night so am down to 36 cards (including the 40, 90) to complete a Green#d to 399 refractor set.
Will buy a new monthly Beckett today. I do not have an online Beckett subscription and I noticed the online prices don't seem to match the monthy Becketts for some odd reason in many cases.
Will try to revisit your list after I pick up a Beckett today and see if I can find something else. Never even heard of Mason Williams
