Yes, sorry to disappoint, this $1 to $100 were made by Borland and are counterfeits. Matching genuine examples do of course exist but the Borlands, as usual, are uncirc, perfectly aligned and the hotstamp differs slightly. These are scarce chips regardless. Price is $20 each shipped. The 25c chip below is genuine. That one is $10 shipped. More info at:
