This is a rhetorical question. Since there are no train shows very convenient to me, what is the consensus on this example of stuff for sale. A Lionel four car aluminum passenger set consisting of #2531, 2532, 2533,and 2534 sell for $300 They are in good shape, are the ones with rounded ribs, and round rivets, no red light on the observation. Greenberg's says these should run from between $147 to $300 depending on condition. This set is clean, no major issues, would probably be classified as 'Very Good'.
If you wanted this set, but could live without out, what would you find this set at a train show for at a price you would consider a fair trainshow price?
