Do record where you got the coins from too, invaluable in the end And you could also add such things as "Variety", "Reference" (Freeman, Peck, Spink etc), "Latest Spink value", "Proof" (Y/N), "Storage" (if you use flips, albums, trays, boxes etc). And if you ever dispose of any, you will want a record of who/where you sold it to, and how much for. You could use Description for toning characteristics, and don't forget having a space for a picture of obverse / reverse.
