Up until now, the card and board games rarity list and price guide listed 3 conditions: M/NM, Excellent, and Good.

We have received feedback from collectors who asked for prices of board games that have never been opened, with the game pieces still sealed. These are worth a lot more then games that are mint/near mint.

Based on this feedback we have added the NIB (New in Box) column to the rarity guide. The price list now features prices for board games in all 4 conditions: NIB, M/NM, Excellent and Good.

Guide currently has over 200 card and board games listed, and we are constantly researching the prices of more card and board games to add to the guide.
