HandsAtNecktlwise12: there are several lower grade n172s on ebay right now which may be available under $100. Even lower grade examples in the $50 - $75 range often are cards which have quite a bit of trimming and no back on them because they perhaps were glued into a scrapbook and had to be skinned out. N172s under $50 are not frequently encountered (by me); but may be an interesting option.
