MONGOLIA. Commercial and Industrial Bank. 1 to 100 Tugrik, 1941. P-21s to 27s.6 pieces in lot. Specimens. This is only the second set of these bright and highly colorful 1941 series specimen notes we have handled. Seen with increasing format size in higher denominations and with solid zero serial numbers and "Specimen," overprint diagonally at center. A few show with a minor handling mark or two but nothing unusual for the grade. Fully original and the last we handled was lot 11452 in our March 2011 auction which brought $5,605.00 against an $800 to $1,200 estimate.Uncirculated
