I also collect cancelled checks, have over 200 different ones from players in all sports,
some entertainers & Presidents.
I also like all forms of cancelled checks, not just a players personal account but payroll & endorsement checks as well.
For my checks, I prefer them unslabbed and only one I have is framed, and that's a Zach Wheat matted w/ a Sporting News premium and a Perez/Steele postcard.
I bought it this way and figured to leave as is.
At one point his check was deemed real tough as one bank statement envelope was uncovered
by his children after his death w/ maybe 25 checks inside.
I have 3, so I'm sure another couple envelopes w/ checks surfaced as his check is routinely offered.
Here's a couple of my HOFers, I have them in large Roop binders w/ a HOF plaque and a Perez/Steele postcard
W/ stickers signifying when they were born & passed away (if applicable) + their HOF induction date.
On the other side of the binder, I have an 8 x 10 photo or magazine cover.
For recent players I have the HOF plaque. P/S postcard & photo's autographed.
