I would make it somewhere between $20 and $25. BTW, the best prices I have found for circulated Lincolns is http://www.numismedia.com/fmv/prices/lnccnt/pricesgd.shtml
Some of those prices are very low, and some are over CDN. Where do they get those figures? $33 for a VF 24-D? Really? LOL The 14-D is $408 for a F, CDN is $330/$360.
