How to Tell If Furniture Is Antique or a Reproduction: 7 Checks That Work Every Time

Construction Methods: How the Piece Was Built

Pre-1860 furniture was built with hand-cut joinery. Dovetail joints (the interlocking fan-shaped cuts at drawer corners) are the single most reliable age indicator. Hand-cut dovetails (pre-1860) are irregular — the pins and tails vary slightly in size and spacing because they were cut by hand with a saw and chisel. Machine-cut dovetails (post-1860) are perfectly uniform — identical spacing, identical angles, identical depth. If the dovetails on a piece are perfectly regular, the drawer was machine-made. French dovetails (rounded, single large dovetail) appeared on cheaper factory furniture from 1890-1940. Box joints (straight, interlocking fingers with no fan shape) are 20th century. Stapled or nailed drawer corners are post-1950 and have no antique value. Look underneath and behind the piece. Pre-1900 furniture has rough, unfinished secondary wood (the wood you do not see — drawer bottoms, backing boards, interior surfaces). This wood was never meant to be seen, so craftsmen did not finish it. Reproductions often have machine-sanded secondary surfaces because modern woodworkers sand everything out of habit. Run your hand along the back panel and drawer bottoms: rough sawmill texture = old. Smooth sanding = modern. Screw analysis: handmade screws (pre-1850) have irregular threads, flat-bottom slots, and off-center slots. Machine-made screws with pointed tips appeared after 1850. Phillips head screws were not invented until 1936 — any piece with Phillips screws is post-1936 or has been repaired. Valued identifies construction era from photos of joinery, hardware, and screws — snap the drawer corner and it tells you the approximate age range.

Hardware: Pulls, Hinges, and Locks Tell the Story

Hardware is one of the easiest things to check and one of the hardest to fake correctly. Original hardware leaves wear patterns on the wood around it — a pull that has been opened 50,000 times over 150 years creates a patina arc on the wood surface where fingers have repeatedly touched. This wear pattern is nearly impossible to replicate convincingly on a reproduction. Brass pulls: cast brass (heavy, with a slightly rough texture on the back) is pre-1850. Stamped brass (thin, with a smooth back) is post-1850. The bail (the swinging handle) should show wear from decades of use — thin spots where fingers grip, a slightly polished surface from repeated contact. New brass pulls on reproductions are uniformly shiny or uniformly tarnished (artificially aged) but lack the specific wear at the grip points. Hinges: hand-forged iron hinges (irregular shape, hammer marks visible) are pre-1830. Cast iron hinges (uniform shape, no hammer marks) are 1830-1900. Steel hinges with screw holes are 20th century. Butt hinges (the standard rectangular hinge inside cabinet doors) replaced strap hinges in the mid-1800s. Locks: original locks on genuine antiques often have a separate escutcheon (the decorative plate around the keyhole) that shows wear from key insertion. The lock mechanism itself should show era-appropriate construction — hand-filed iron for pre-1850, cast mechanisms for 1850-1920. Replacement locks are common and do not disqualify a piece as antique, but they should be disclosed. The hardware test: if all the hardware on a piece looks brand new and uniform, it is either a reproduction or the hardware has been entirely replaced. On a genuine antique, at least some hardware shows era-consistent wear, even if individual pieces have been replaced over the years.

Wood Aging: Shrinkage, Oxidation, and Patina

Wood shrinks as it ages — and it shrinks differently across the grain than along the grain. A tabletop that was perfectly round when made in 1820 is now slightly oval (measurably so — 1/4 to 1/2 inch difference between the dimensions). Drawer bottoms that were flat are now slightly cupped. Panels that fit flush in their frames now show slight gaps on two sides (the sides perpendicular to the grain direction, where shrinkage is greatest). These dimensional changes cannot be faked because they require centuries of moisture cycling. Oxidation darkens exposed wood surfaces over time. The inside of a drawer that has been opened to air for 150 years is noticeably darker than the bottom of the same drawer (which was sealed against the frame and received no air exposure). Remove a drawer and compare the exterior surface color to the interior surface under the runner — the difference should be dramatic on genuine antiques (dark exterior, light interior). On reproductions, both surfaces are similar because the wood has not had time to develop differential oxidation. Patina is the overall surface aging: a combination of oxidation, UV exposure, wear, wax buildup, and absorbed grime that creates a depth and warmth that new wood simply does not have. Genuine patina has a translucent quality — you can see the wood grain through the aged surface. Fake patina (applied stains, tinted finishes, or artificially distressed surfaces) sits ON the wood like a coating rather than IN the wood. The UV test: turn the piece over or look at the back. The underside, which has been shielded from sunlight, should be lighter than the top surfaces. On a genuine antique table, the bottom of the top is noticeably lighter than the top surface — 100+ years of UV exposure creates this difference. On a reproduction stained to look old, both surfaces are roughly the same color because the color comes from stain, not from UV aging.

Wear Patterns: Where People Actually Touched the Piece

Genuine wear tells a story of use. A chair shows wear on the front edge of the seat (where people sat), the top of the arms (where hands rested), and the stretchers (where feet rested). A table shows wear on the top surface (especially around the edges where arms and dishes rested) and the bottom of the legs (where they contacted the floor). A dresser shows wear around the pulls (from opening drawers) and on the top surface (from setting things down). The wear patterns on genuine antiques are asymmetric and specific — they correspond to how the piece was actually used. The right side of a desk may show more wear than the left (right-handed user). The front legs of a chair may be more worn than the back (rocking forward while sitting). The top drawer of a dresser may show more pull wear than the bottom drawers (used more frequently). Fake distressing (intentional damage to make furniture look old) typically produces symmetric, uniform wear that does not match real use patterns. Sandpaper distressing creates wear in logical places but lacks the depth and specificity of genuine wear. Beating the wood with chains (a common reproduction technique) creates random dents that do not correspond to any real use pattern — no one beats their furniture with chains during normal use. The floor test: genuine antique legs show uneven wear on the bottom — the leg that was on a lower floor spot is more worn than the others. Reproductions have uniformly worn or uniformly distressed leg bottoms. Also check for water damage rings on the bottom of legs — genuine furniture that sat on real floors for 100+ years often has moisture marks from floor cleaning. Valued identifies genuine vs fake wear patterns from photos — snap the wear areas and it assesses authenticity based on the pattern distribution.
