Sorry to be a tad late in commenting, but I'll blame that dastardly Covid.
A Conehammer is the only Broomie (other than the first spur hammer babies that cost a fortune and are extremely rare) that qualifies as an antique, which is the manufacture no later than December 31, 1897. I had a restricted Conehammer before that date, and I supplied the CFO with the web site at hand. My Conie was duly changed to antique status.
The highest number that makes it under the end of 1897 is 12199. Above that, and it's manufactured in 1898 or later.
I know from experience, selling guns at auction, a certain Ontario auctioneer charges 15% to purchasers, but 25% to consignors. Ouch! I'm old enough to remember prior to the Internet, when commissions were very low, or non existent. The 'Net has opened up the sale of an item to the rest of the planet, yet auction houses increase their commission fees. Good old human greed.
As for value, there are two presently for sale that I know of, at the same location: one has some original finish with matching stock asking $7500, and the other Coney is refinished with non-matching stock for $6,000, not including taxes.
If you buy one up here, plan to keep it. You'll never make money on it in Canada, and the paperwork and aggravation to sell it at auction in the States may not give you the money that you want.
On that cheery note, let's get our gun shows back in business, shall we?
Cheers,
Bill
